Question

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

Professor PC Thomas Classes · Answer

Flux entering the cylinder.\ $\phi_{1}=\mathrm{EA}$ where A is the area of cross section and E is the electric field.\ The flux leaving the cylinder $\phi_{2}=-\mathrm{EA}$\ $	herefore$ Total flux $=0$\
