Question

A cyclotron is used to accelerate protons (${}^1_1\text{H}$​), Deuterons (${}^2_1\text{H}$​) and α-particles (${}^4_2\text{He}$). While exiting under similar conditions, the minimum K.E. is gained by

• A. α-particle
• B. Proton
• C. Deuteron
• D. Same for all

Answer 1

Answer: (C)

Deuteron

Answer 2

The correct option is (C): $K.E. =\frac{q^2}{m}$
So a deuteron gains the least kinetic energy.
