MHT CET 2026 Physics question

In the cyclotron, as radius of the circular path of the charged particle increases, ( = angular velocity, V = linear velocity)

(A)V increases, decreases.
(B)V increases, remains constant.Correct
(C)only increases , V remains constant.
(D)both and V increase.

Answer: (B)

Solution

In a cyclotron the particle moves in a circle of radius , so and the linear velocity increases in proportion to the radius. The angular velocity is , which depends only on the charge-to-mass ratio and the magnetic field, so it stays
