What is the physical meaning of charge density on lines or on areas?
Every object consists of a certain amount of positive charge and a certain amount of negative charge. For neutral objects, the amount of each type of charge is equal in every tiny, or infinitesimal, portion of the object. If the object has the shape of a line, the amount of positive charge in each tiny segment of length along the line is equal to the amount of negative charge in each tiny segment of length. For a neutral three-dimensional object, such as a cube, the amount of negative charge in each small volume element of the total volume of the cube is equal to the amount of positive charge in each small volume element. All neutral objects have a charge density of zero throughout their volumes despite the fact that they have charge. The charge density describes the amount of excess charge per given region of space. For objects that are not neutral, then, the charge density is either positive or negative. A positive charge density expresses the fact that an object has a given amount of positive charge more than it has negative charge in a specific region of space. Likewise, a negative charge density means the object has a given amount of negative charge more than positive charge for a given region of space. For a line of charge, the charge density is expressed as Coulombs per meter when using SI units. For a two-dimensional object, such as a disk, the charge density using SI units is Coulombs per (meter^2). For objects that have uniform excess charge throughout their volume, the charge density is expressed as the total amount of excess charge on the body divided by the total length/ area/ volume of the body. For objects that have nonuniform charge excesses, the charge density must be expressed as a function of position (and possibly, time) within the object.
Is plastic wrap a positive or a negative?
It is a negatively charged object
How do you make negative Charge?
by taking a negatively charged object and touching it with the object that you want to be charged
Why is gravitational potential always negative?
because gravity is a force that acts down on an object. In physics up is positive and down is negative
How are positive numbers used in real life situations?
The measurement of a length of an object is always a positive number.
Is there any negative charge on a positive charged object?
Any "object" larger than elementary particles consists of positive and negative charges. If your object has a negative charge, it simply has more particles with a negative charge than particles with a positive charge.
Which particles moves when an object acquires a net positive or negative charge?
Electrons are the particles that move when an object acquires a net positive or negative charge. In the case of a positive charge, electrons are removed from the object, leaving an excess of positive charge. Conversely, in the case of a negative charge, electrons are added to the object, creating an excess of negative charge.
How can an object have a neutral charge if part of the object has a positive and a negative charge?
If an object has both positive and negative charges in different regions, it can still have an overall neutral charge if the total amount of positive charge is equal to the total amount of negative charge. This results in a cancellation of the charges, making the object neutral overall.
When there is an equal amount of positive and negative charges on an object what is the net charge of the object?
The net charge of an object with equal amounts of positive and negative charges is zero. Positive and negative charges cancel each other out, resulting in no overall charge on the object.
What kind of charge does an object have if it has more negative particles than positive particles?
The object would have a negative charge. Negative particles, such as electrons, carry a negative charge when they outnumber the positive particles, such as protons.
Is an object without a charge repelled by both positive and negative charges?
Positive and negative charges would have not effect on an object without charge.
How can one determine the net charge of an object or particle?
The net charge of an object or particle can be determined by adding up the positive and negative charges present on the object or particle. If the total positive charges are greater than the total negative charges, the object or particle has a positive net charge. If the total negative charges are greater, it has a negative net charge. If the positive and negative charges are equal, the object or particle has a neutral net charge.
What is A POSITIVE OR NEGATIVE charge produces a net charge on a object?
A positive or negative charge produces a net charge on an object when there is an imbalance of electrons (negative charge) or protons (positive charge) within the object, resulting in an overall excess of one type of charge. This excess charge creates an electric field around the object and can interact with other charged objects.
What charge does an object have if it has more negative particles than positive particles?
The object would have a negative charge if it has more negative particles than positive particles. This is because the excess negative particles result in an overall negative charge.
Is it true that an object with a positive charge will attract another object with a negative charge?
yes
Is an object's net charge positive or negative if it loses electrons?
An object's net charge becomes positive if it loses electrons because it has an excess of positive protons relative to negative electrons.
What is true about the number of positive and negative charges in a charged object?
A charged object can have an unequal number of positive and negative charges, resulting in a net charge. An object with more positive charges than negative charges will have a positive net charge, and vice versa for negative charges.
