Three charges `Q_(0) , - q ` and `-q` are placed at the vertices of an isosceles right angle triangle as in the figure. The net electrostatic potential energy is zero if Q 0 is equal to :

A

`(q)/(4)`

B

`(q)/( 2 sqrt(2))`

C

`sqrt(2q)`

D

`+q`

Text Solution

Verified by Experts

The correct Answer is:
B
`- (K Q_0 q)/l- (Kq^2)/l+(Kq Q_0)/(sqrt2 l)=0 implies q= + q/(2 sqrt2)`
