Question

100 J of work is done to move a charge of 5 C from a point where potential is 20 volts to a place where potential is V. Find V.

Answer 1

Answer:

40 V

Explanation:

Let the potential at the point be Vb

Vb-Va=W/q (where Vb-Va is the electric potential energy difference)

therefore,

Vb-20=100/5

Vb-20=20

Vb=40 V
