NEET Physics Electric Flux MCQ Question
Consider a right circular cylinder with a uniform electric field E in the positive x direction for x > 0 and E in the negative x direction for x < 0. The cylinder has a length of 20 cm and a radius of 5 cm, centered at the origin with its axis along the x-axis. One face is at x = +10 cm and the other at x = -10 cm. Which of the following correctly describes the net electric flux through the curved surface of the cylinder?
The net electric flux through the curved surface is zero.
The net electric flux through the curved surface is maximum.
The net electric flux through the curved surface is equal to the charge enclosed.
The net electric flux through the curved surface is equal to the product of E and the cylinder's volume.
Correct Answer
Detailed Explanation
The electric field lines are parallel to the curved surface of the cylinder, thus the electric flux through the curved surface is zero as per Gauss's law.
