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.
How can an object have a neutral charge if part of the object has a positive and a negative charge?
If the positive and negative charges are equal, then the object has a 'net' neutral charge.
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.
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.
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?
positive
How does an object get a positive charge or negative charge?
By loosing or gaining and electron.
Is charge the measure of extra positive or negative particles in an object?
positive
When an object has more negative charge than positive charge what is it called?
The object is named an 'ANION'. A CATION has positive charge. Collectively they are named as 'IONS'.
How is discharging in a positive object different in a negative object?
The direction of the flow of electric current. In a positive object, electrons flow to it because it has an abscence of negative charge (aka electrons). In a negative object, it has an abundance of negative charge (electrons) so electrons flow away from it.
What charge does an object have if it has more negative particles than positive particles?
negative
Does an electroscope identify if an object has a positive or negative charge or does it just indicate that an object has a charge?
Alll an electroscope does is tell you if there is charge
Is an object that has no electric charge as a whole is negative or positive?
No. It is neutral.
