Question

On moving a charge of 40 C by 2 cm, 2J of work is done. Then the potential difference between the points is

Answer 1

Answer:

Explanation:Potential difference between two points is given by

Va - Vb = W/q0

Work, W = 2 J

Charge, q0 = 20 C

Potential difference = 2/20 = 0.1 V

hope it help you

Answer 2

v = w/ q = 2/40= 1/20volt
