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 the reason is the correct explanation of the assertion.

B

If both assertion and reason are true but reason is not the correct explanation of the 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 penetrating power is maximum in case of gamma rays because gamma rays are electromagnetic radiations of very small wavelength.
