Question

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

Answer 1

Correct Answer - 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.
