Question

An electron is allowed to move with constant velocity along the axis of current carrying straight solenoid. (A) The electron will experience magnetic force along the axis of the solenoid. (B) The electron will not experience magnetic force. (C) The electron will continue to move along the axis of the solenoid. (D) The electron will be accelerated along the axis of the solenoid. (E) The electron will follow parabolic path-inside the solenoid. Choose the correct answer from the option given below:, B, C and D only, A and D only, B and C only, B and E only

MARKS App · Accepted Answer

The Lorentz force is given by F → = q ( v → × B → ) = q v B sin θ n ^ . The angle θ = 0 ° . Hence the force experienced is zero. Thus, the electron will not experience any magnetic force and the electron will continue to move along the axis.
