The mass of a proton is 1.0089\(\mu\) and that of a neutron is 1.0089\(\mu\). Determine the energy evolved in stabilizing the nucleus of nitrogen of mass number 14 with 7 protons and 7 neutrons. [speed of light = 3.0 x 108ms-1; 1\(\mu\) = 1.67 x 10-27kg]

A.

1.710 x 10-8J

B.

3.131 x 10-8J

C.

1.476 x 10-8J

D.

2.332 x 10-9J

Correct answer is D

E = DMC2 = 14,1141 x 1.67 x 10-27 x 9 x 1016

= 2.332 x 10-9J
