AIPMT PRELIMS 2006 Physics Magnetic Force on a Moving Charge MCQ Question
Type: MCQ-conceptual-Medium-Class 12
When a charged particle moving with velocity is subjected to a magnetic field of induction B, the force on it is non-zero. This implies that:
A
angle between v and B is necessarily 90°
B
angle between v and B can have any value other than 90°
C
angle between v and B can have any value other than zero and 180°
D
angle between v and B is either zero or 180°
Correct Answer
Option C
Detailed Explanation
The magnetic force on a charged particle is given by F = q(v × B), which is maximum when the angle between v and B is 90°. Therefore, for the force to be non-zero, the angle must be 90°.
