Question

What is the electric potential energy of a charge that experiences a force of 3.6x10^-4 N when it is 9.8x10^-5 m from the source of the electric field?
A) 3.5x10^-8 J
B) 4.6x10^-4 J
C) 2.7x10^-1 J
D) 3.7x10^0 J

Answer 1

Answer:

3.5 x 10^-8 J

Explanation:

We are given,

force experienced by a charge = 3.6 x 10^-4 N; and

distance of charge from the source of electric field =  9.8 x 10^-5 m

We know that, Energy = force x distance

therefore, to find the potential energy of the charge, we need to multiply its applied force with the given distance to get:

Electric potential energy of a charge = (3.6 x 10^-4) × (9.8 x 10^-5) = 3.5 x 10^-8 J

Therefore, the potential energy of a charge is 3.5 x 10^-8 J.
