NEET Physics Electric Flux MCQ Question
Consider a right circular cylinder of length 20 cm and radius 5 cm, centered at the origin with its axis along the x-axis. The electric field is uniform in the positive x direction for x > 0 and uniform in the negative x direction for x < 0, both with a magnitude of 200 N/C. What is the total electric flux through the curved surface of the cylinder?
Zero
100 Nm²/C
200 Nm²/C
400 Nm²/C
Correct Answer
Detailed Explanation
The electric flux through the curved surface of the cylinder is zero because the electric field lines are parallel to the surface, resulting in no perpendicular component and thus no contribution to the flux.
