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



By process​

Answer 1

Answer:

v = joule / coulomb

= 100 j / |-5 c |

= 100 /5

= 20 v
