Question

Two electric charges of 9µC and −3µC are placed 0.16m apart in air. There will be a point P at which electric potential is zero on the line joining the two charges and in between them. The distance of P from 9µC charge is

1. 0.14m 

2. 0.12m 

3. 0.08m 

4. 0.06m

Answer 1

Correct Option : 2

Explanation :

Let P be at distance x from the charge 9µC . The distance of P from the charge - 3µC will be 0. 16-x
