Three charges each +q, are placed at the corners of an isosceles triangle ABC of sides BC and AC, 2a D and E are the mid point of BC and CA. The work done in taking a charge Q and D to E is :

A

`(3qQ)/(4pi epsi_(0)a)`

B

`(3qQ)/(8pi epsi_(0)a)`

C

`(qQ)/(4pi epsi_(0)a)`

D

zero

Text Solution

Verified by Experts

The correct Answer is:
D
As this triangle is isosceles, AD= BE. Hence, potential due to given charge is same at D and E and there will be no work moving chrge Q from D to E
