A negative charge is moved by an external agent in the direction of electric field. Then
.

A

Potential energy of the charge increases.

B

Potential energy of the charge decreases.

C

Positive work is done by the electric field

D

negative work is done by the electric field

Text Solution

Verified by Experts

The correct Answer is:
a.,d.
When a negative charge moves from high potential to low potential, its potential energy increases.
`W_(e 1) = q(V_1 - V_2)`
As `V_1 gt V_2` and `q` is negative, `W_(e 1)` is negative.
