A proton, a deutron and alpha-particle, ...

A proton, a deutron and `alpha`-particle, whose kinetic energies are same, enter perpendicularly a uniform magnetic field. Compare the radii of their circualr paths.

A

`1:1`

B

`2:1`

C

`1:2`

D

`4:1`

Text Solution

Verified by Experts

The correct Answer is:
A
`R = (sqrt(2mK))/(Bq), (R_(p))/(R_(alpha)) = (sqrt(m))/(e).(2e)/(sqrt(4m)) = (1)/(1)`
