When two charges are brought close together the electric potential energy of the pair of charges is?

If you bring two positive charges or two negative charges closer, you have to do positive work on the system, which raises their potential energy. Since potential energy is proportional to 1/r, the potential energy goes up when r goes down between two positive or two negative charges.

What is the potential energy of the pair of charges?

To find the total electric potential energy associated with a set of charges, simply add up the energy (which may be positive or negative) associated with each pair of charges.

How do you find the electric potential energy between two charges?

V = k × [q/r] Where, V = electric potential energy. q = point charge. r = distance between any point around the charge to the point charge.

How are electric potential and electric potential energy related?

The basic difference between electric potential and electric potential energy is that Electric potential at a point in an electric field is the amount of work done to bring the unit positive charge from infinity to that point, while electric potential energy is the energy that is needed to move a charge against the …

How is potential energy related to electric potential?

Electric potential is the amount of potential energy per unit of charge. When work is done on a positive test charge to move it from one location to another, potential energy increases and electric potential increases.

How do you find potential energy from electric potential?

When such a battery moves charge, it puts the charge through a potential difference of 12.0 V, and the charge is given a change in potential energy equal to ΔPE = qΔV. So to find the energy output, we multiply the charge moved by the potential difference.

Is electric potential energy negative?

Note that the electrical potential energy is positive if the two charges are of the same type, either positive or negative, and negative if the two charges are of opposite types. This makes sense if you think of the change in the potential energy ΔU as you bring the two charges closer or move them farther apart.
