A uniformly charged and infinitely long ...

A uniformly charged and infinitely long line having a liner charge density `lambda` is placed at a normal distance y from a point O. Consider a sphere of radius R with O as the center and Rgty. Electric flux through the surface of the sphere is

A

Flux crossing the sphere is zero if d gt R b)

B

Flux crossing the sphere is `(2lambdasqrt(R^(2)-d^(2)))/(epsilon_(0))` , if `d lt R`

C

If `d gt R`, the magnitude of maximum potential difference two points on the sphere is `(lambda)/(2piepsilon_(0))"In"((d+R)/(d-R))`

D

When a charge is moved along any dimeter of the sphere in the plane perpendicular to the wire, work done is zero.
