A cylinder of radius R of length L is placed in a uniform electric field E parallel to the cylinder axis. The total flux for the surface of the cylinder is given by

Options

A. `2piR^(2)E`
B. `piR^(2)//E`
C. `(piR^(2)//piR)//E`
D. zero

Answer

D

Explanation

Total flux through cylinder is `phi_(E)=intEdScos90^(@)=0`
