When a charged particle is placed in a time varying magnetic field, there is an induced electric field which changes the energy of the particle.
So statement (1) is false.
But if there is no change in magnetic field (constant magnetic field) there is no induced electric field.
So statement (2) is true.
Ans : (b)
