Question

A cylinder of length Land radius $R$, whose axis is parallel to electric field. Find the total electric flux ejected from the surface of cylinder:

• A. $2\pi R^{2}E$
• B. $\pi R^{2}L/E$
• C. $\pi R^{2}LE$
• D. zero

Answer 1

Answer: (D)

Cylinder is placed parallel to the electric field, so the electric flux ejected from the surface of cylinder is zero.
