When a charge is moved against the Coulomb's force of an electric field, then

A

work is done by the electric field

B

energy is used from some outside source

C

strength of field decreases

D

energy of the system is decreased

Text Solution

Verified by Experts

The correct Answer is:
A
Work is done by the electric field because ` theta = 0^(@), W = F s cos theta to ` positive .
