Question

A proton and an a-particle enter a uniform magnetic field
perpendicularly with the same speed. If proton takes 25 μ
second to make 5 revolutions, then the time period for the
a-particle would be
(a) 50 μ sec (b) 25 μ sec
(c) 10 μ sec (d) 5 μ sec

Answer 1

Answer:

Hence the answer is this
