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 sphereis zero if `d gt R`

B

flux crossing the sphere is `(2lsqrt(R^(2)-d^(2)))/(epsilon_(0))"if"dltR`

C

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

D

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