Amongst alpha,beta and gamma-particles, ...

Amongst `alpha,beta` and `gamma-`particles, `alpha-`particle has maximum penetrating power.
The `alpha-`particle is heavier than `beta` and `gamma-`particle.

A

If both assertion and reason are true and reason is the correct explanation of assertion.

B

If both assertion and reason are true but reason is not the correct explanation of assertion.

C

If assertion is true but reason is false

D

If assertion is false but reason is true.

Text Solution

Verified by Experts

The correct Answer is:
D
(d) The penetrating power is maximum in case of `gamma-`rays because `gamma-`rays are electromagnetic radiotion of very high frequency.
