NEET Physics Electric Flux MCQ Question
A right circular cylinder of length 20 cm and radius 5 cm has its axis along the x-axis with one face at x = +10 cm and the other at x = -10 cm. If the electric field is uniform and given by E = 200 ˆ i N/C for x > 0 and E = -200 ˆ i N/C for x < 0, what is the electric flux through the curved surface of the cylinder?
0 N m^2/C
100 N m^2/C
200 N m^2/C
400 N m^2/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 curved surface, resulting in no net flow through it.
