NEET Physics Electric Flux MCQ Question
A right circular cylinder of length 20 cm and radius 5 cm is placed with its axis along the x-axis, with its center at the origin. The electric field is uniform and given by E = 200 ˆi N/C for x > 0 and E = -200 ˆi N/C for x < 0. What is the electric flux through the curved surface of the cylinder?
0 N m²/C
100 N m²/C
200 N m²/C
400 N m²/C
Correct Answer
Detailed Explanation
The electric flux through the curved surface is zero because the electric field is parallel to the curved surface area, and hence, no field lines pass through it.
