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.
