Show Answer
Solution:
Ans. Correct option : (a)
Explanation : In a cyclotron, a charged particle describes the circular path inside the dees and is accelerated while going from one dee to another due to the electric field. While moving in the circular path, charged particles have centripetal acceleration which is provided by the magnetic force due to the magnetic field. A charged particle undergoes acceleration all the time, inside the cyclotron.
