Which among alpha and beta particles have higher ionising power and why?
Assertion (A) : beta -particles have greater penetrating power than alpha -rays but less than gamma -rays Reason (R ) : beta -particles are lighter than alpha -rays but heavier than gamma -rays
(A) alpha -rays have greater ionising power the beta (R ) alpha -particles carry 2^(+) charge while beta -particles carry only I^(-) charge.
Assertion (A): beta- particles have greater penetrating power than alpha- rays but less than gamma- rays. Reason (R) : beta- particles are lighter than alpha- particles but heavier than gamma.
