Question

what is e=mc^2 Explain in detail

Answer 1

e = energy
m= mass
c= speed of light in vaccum
Hence,
energy= mass × speed of light in vaccum.

Answer 2

It is the famous equation given by physicist Albert Einstein. It is called Einstein's theory of special relativity.This equation gives the relationship between mass and energy.
It means Energy ( e) is equal to mass (m) multiplied by speed of light squared (c).
This equation is widely used by nuclear power plants..
