Question

Inside a cyclotron, a charged particle is subjected to both an electric field and a magnetic field. It gains kinetic energy due to (A) only the electric field (B) only the magnetic field (C) both the fields (D) none of the fields.

Tardigrade Admin · Accepted Answer

Magnetic force does no work on the charged particle. Hence, gain in kinetic energy of a charged particle in a cyclotron depends only on electric field.
