Question

How does the direction of magnetic force on a negative charge compare with that on a positive charge moving with the same velocity in the same magnetic field?

विकल्प

• It is in the opposite direction.

• It is always along the velocity.

• It is in the same direction.

• It is always along the magnetic field.

Answer 1

Reversing the sign of the charge reverses the direction of magnetic force. The comparison assumes the velocity and magnetic field remain unchanged.
