the total flux of electric lines of forces of a charge q placed at the mid point of the dge of a side of rectangular box, as shown in figure through the box is

A

`(q)/(2in_(@))`

B

`(q)/(4in_(@))`

C

`(q)/(8in_(@))`

D

`(q)/(16in_(@))`

Text Solution

Verified by Experts

The correct Answer is:
B

The charge q is completely closed by four identical given box. Therefore, the required flux `=(1)/(4)(q)/(in_(0))`
