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.
How do you multyply integers?
when you have a negative times a negative it will equal a positive but when you have a negative times a positive it will equal a negative no matter what!
Does a negative divided by a negative equal a negative?
It is a positive.
Does a negative plus a negative equal a postive?
No, a negative plus a negative is a negative
Is negative 4.3 equal to negative 4.03?
No. They are different numbers, so they are not equal.
Is the charge of a electron always equal to the charge on a neutron?
No, the charge of an electron is negative (-1) while the charge of a neutron is neutral (0).
Does all matter have a negative or positive charge?
No, not all matter has a negative or positive charge. Matter can be neutral, meaning it has an equal number of positive and negative charges, such as in most atoms. Charged particles exist in matter, such as electrons with a negative charge and protons with a positive charge.
An object that does not contain equal amounts of positive charge and negative charge has a what?
An object that does not contain equal amounts of positive charge and negative charge is considered to be charged. It may have a net positive charge (if it has more positive charges) or a net negative charge (if it has more negative charges).
When ions having a positive charge form bonds with ions having a negative charge the charge on the resulting compound is what?
The charge is 0 if the positive and negative charges were equal
Electrons have what type of a charge?
All electrons have an equal negative charge (-1 standard electron charge), which is opposite to the standard proton charge (+1).
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.
Do an electron has an negative charge?
Yes, an electron has a negative charge. It carries a fundamental unit of negative electrical charge approximately equal to -1.6 x 10^-19 coulombs.
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.
What objects with equal amounts of positive and negative charge are said to be electrically?
An object with equal amounts of positive and negative charge is electrically neutral.
What will be the charge of an atom be if it has an equal number of positive and negative charges?
Neutral - the atom will have no charge.
Why is every atoms charge 0?
you equal negative and positives.
Electrons carries a positive or negative charge?
Yes, they have a negative charge. Protons have a positive charge and neutrons have no charge, they are neutral.
