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:
- (1) B, C and D only
- (2) A and D only
- (3) B and C only
- (4) B and E only
Correct answer: (3) B and C only
Solution
The correct options B and C are accurate because an electron moving with constant velocity along the axis of a current-carrying solenoid does not experience a magnetic force, as the magnetic field inside the solenoid is uniform and parallel to the axis, resulting in no force acting on the electron. Therefore, it will continue to move along the axis without any acceleration.
