AIPMT PRELIMS 2009 Physics Magnetic Force on a Moving Charge MCQ Question
Type: MCQ-conceptual-Medium-Class 12
The magnetic force acting on a charged particle of charge −2 μC in a magnetic field of 2T acting in y direction, when the particle velocity is (2î + 3ĵ) × 10⁶ ms⁻¹, is:
A
4 N is z direction
B
8 N is y direction
C
8 N in z direction
D
8 N in −z direction
Correct Answer
Option D
Detailed Explanation
The force on a charged particle moving in a magnetic field is given by F = q(V × B). Substituting the given values, the force is calculated a N in the z-axis direction.
