An infinite wire having charge density `lambda` passes through one of the edges of a cube having length l. find the total flux passing through the cube

A

`(lambdal)/(epsilon_(0))`

B

`(lambdal)/(4epsilon_(0))`

C

`(lambdal)/(6epsilon_(0))`

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
B
Total flux from line charge
`=(q)/(epsilon_(0)) = (lambdal)/(epsilon_(0))`
Flux through cube `= (1)/(4)th` of total flux `= (1)/(4) xx (lambdal)/(epsilon_(0)) = (lambdal)/(4epsilon_(0))`
