A charge particle is moved along a magnetic field line. The magnetic force on the particle is
Text Solution
Verified by ExpertsThe correct answer is:
D
The force on a charged particle 
moving with velocity 
in a magnetic field 
is given by
As the charge is moving along the magnetic line of force, the velocity and magnetic field vectors will point in the same direction, making a cross product.
So, the magnetic force on the particle will be zero.
