What is the correct order of velocity of alpha `(alpha) and, " beta " (beta)` and gamma `(gamma)` rays

A

`alpha gt beta gt gamma `

B

`alpha gt gamma gt beta`

C

`gamma gt alpha gt beta`

D

`gamma gt beta gt alpha`

Text Solution

Verified by Experts

The correct Answer is:
D
The velocity of `alpha` rays are ~ `1/(10)` th of that of light , that of `beta`-rays are ~`1/3` to `9/10` th of that of light . The velocity of `gamma` rays are same as that of light.
