Assertion: Between alpha, beta and gamma...

Assertion: Between `alpha, beta and gamma` radiations, penetrating power of `gamma`-rays is maximum.
Reason : Ionising power of `gamma`-rays is least.

A

(a) If both Assertion and Reason are true and Reason is correct explanation of the Assertion.

B

(b) If both Assertion and Reason are true but Reason is not the correct explanation of Assertion.

C

(c) If Assertion is true, but the Reason is false.

D

(d) If Assertion is false but the Reason is true.

Text Solution

Verified by Experts

The correct Answer is:
B

`alpha`-particles are heaviest. Hence, its joinizing power is maximum.
