Question

Positive and negative charges of equal magnitude lie along the symmetry axis of a cylinder. The distance from the positive charge to the left - end cap of the cylinder is the same as the distance from the negative charge to the right - end cap.

What is the flux of the electric field through the closed cylinder ?
A. zero
B. `+ Q//epsilon_(0)`
C. `+ 2Q//epsilon_(0)`
D. `- Q//epsilon_(0)`

Answer 1

Correct Answer - A
Net charge enclosed by the cylinder is zero , so flux through the cylinder is zero.
