Sulphur `35`(34,96903 amu) emits a `beta-` particles but no `gamma`-rays. The product is c hlorine `-35` (`34,96885` amu),. The maximum energy carried by `beta-` particle is:

A

0.016767 MeV

B

1.6758 MeV

C

0.16758 MeV

D

16.758 MeV

Text Solution

Verified by Experts

The correct Answer is:
C
Mass defect = mass of sulphur – mass of chlorine
=34.96903 - 34.96885 = 0.00018 g
Binding energy = mass defect `xx 931`
`= 0.00018xx931 = 0.1675 ` MeV
