NEET Physics Electric Flux MCQ Question
A right circular cylinder of length 20 cm and radius 5 cm is centered at the origin with its axis along the x-axis. An electric field is uniform and in the positive x direction for x > 0 and in the negative x direction for x < 0, with magnitude 200 N/C. What is the net electric flux through the curved surface of the cylinder?
Zero
200 π N m²/C
100 π N m²/C
400 π N m²/C
Correct Answer
Detailed Explanation
The net electric flux through the curved surface of the cylinder is zero because the electric field is parallel to the surface, resulting in no perpendicular component of the field through the surface.
