Assertion:Among alpha, beta and gamma rays, `alpha`-particle has maximum penetrating power.
Reason: The `alpha`-particle is heavier than `beta` & `gamma` rays

A

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

B

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

C

If Assertion is true, but the reason is false.

D

If Assertion is false, but the reason is true.

Text Solution

Verified by Experts

The correct Answer is:
4
Explanation: The penetrating power is maximum in case of gamma rays because gamma rays are an electromagnetic radiation of very small wavelength.
