A charged particle of charge q is moved ...

A charged particle of charge q is moved around a charge +q along a circular path of radius 'r' from A to B.The work done is

A

`qq_(0)/4 pi varepsilon_(0)r`

B

`2qq_(0)/4 pi varepsilon_(0)r`

C

`2qq_(0)/4 pi varepsilon_(0)r^2.phi r`

D

Zero

Text Solution

Verified by Experts

The correct Answer is:
D
points A and B have the same potential, so the work done is zero.
