A particle of mass m and charge -q is ...

A particle of mass `m` and charge `-q` is released from rest in a uniform electric field. If there is no other force on the particle, the dependence of its potential energy on the distance `x` travelled by it is correctly given by (assume initial potential energy to be zero ,graphs are schematic and not drawn to scale)

A

B

C

D

Text Solution

Verified by Experts

The correct Answer is:
B
`W_(c) = -triangle U` W("c") = U_(i) - U_(f)`
`W_(c) = 0 - U_(f) -qEx = `U_(f)`
