Question

On which law is the nuclear energy explained?

(a) Einstein’s law

(b) Newton’s law

(c) Rutherford law

(d) Mendeleev law

I have been asked this question in a national level competition.

My question comes from Atomic Structure in chapter Nuclear Power Plant of Energy Engineering

Answer 1

The correct answer is (a) Einstein’s law

To elaborate: The nuclear energy is explained the basis of Einstein’s law, one atom may be transformed into another by losing or acquiring some of the above sub-particles. This results in mass change Δm and enormous amount of energy is released (or absorbed).  According to Einstein’s law,

     ΔE = Δmc^2

      Where, c=light of speed.
