Statement-1: Work done in moving a charge with increasing velocity in a steady non-uniform magnetic field may be zero.

Statement-2: Magnetic force is always perpendicular to velocity of charged particle moving in a magnetic field.

Answer:

Solution:

Since the speed is increasing, the kinetic energy is increasing.

$W_{total} = Δ K > 0$

So the total work done cannot be zero; Statement-1 is false.

Magnetic force is always perpendicular to velocity, so Statement-2 is true.
