Question

A work of 100 joule is performed in carrying a charge of –5 C from infinity to a particular point in an

electrostatic field. The potential of this point is.

(A) 100 volt (B) 5 volt (C) –20 volt (D) 20 volt​

Answer 1

Answer:

(C)

Explanation:

Given

energy=100J

charge=-5C

electric potential=energy/charge

=-20V

('-'indicates that the charge is negative)
