question_answer

A cylinder of radius R and 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 [CPMT 1975; RPMT 2002; KCET 2004]

A)                                                 

B)           

C)                   

D)                                      Zero

Correct Answer: D

Solution :

                   Flux through surface A  and Flux through curved surface C = 0 \ Total flux through cylinder = 0
