Question

A proton and an alpha particle are projected with velocity

Answer 1

A proton and an alpha-particle are projected with velocity v0 =(ke^2/ml)^1/2

each, when

they are far away from each other, as shown. The distance between their initial

velocities is L. Find their closest approach distance, mass of proton=m, charge=+e,

mass of a-particle = 4m, charge = + 2e.

Answer 2

Answer:

Here is your answer

frequency,ν=qB/2πm where q ia charge and m is mass of the particle.

For proton ν

p=eB/2πm

and for alpha particle ν

a

=(2e)B/2π(4m)=ν

p/2
