Question

A charge moves from pount A to point B in an electric field. what is true about the potential energy of the charge?

A) it is independent of the value of the charge and its position
B) it is dependent on the value of the charge and its position
C) it remains constant as the charge moves
D) it becomes zero as soon as the charge moves

Answer 1

I'm going to have to say its B

Answer 2

B) it is dependent on the value of the charge and its position

Step-by-step explanation:

As we know that electrostatic potential energy is given by the formula

`U = (kq_1q_2)/(r)`

here we know that electric potential due to one charge on the position of other charge is given by the equation

`V = (kq_1)/(r)`

so potential energy can be given by the formula

`U = q_2 V`

so here potential of a given position will be different so it is dependent on the position of charge

also potential energy depends on the magnitude of charge

so correct answer will be

B) it is dependent on the value of the charge and its position
