A proton, a deutron and a a-particle having the same kinetic energy are moving in circular trajectories in a constant magnetic field. If rp, rd and ra denoted respectively be the radii of trajectory of those particles. Then-
A
ra = rp<rd
B
ra>rd>rp
C
ra = rd>rp
D
rp = rd= ra
Answer
ra = rp<rd
Explanation
Solution
r = qB2m(KE)
