A cylinder of radius rand length `l` is placed in an uniform electric field E parallel to the axis of the cylinder. The total flux for the surface of the cylinder is given by

Options

A. `zero`
B. `2pir^(2)E`
C. `pir^(2)E`
D. `(pir^(2)(+pil^(2))E`

Answer

A

Explanation

Flux = E. ds where ds is area vector Since the angle between electric field and surface of cylinder is `90^(@)`. Therefore total flux from surface of cylinder is zero.
