Question

prove E=mc^2

Eisenstein's mass energy relation

Answer 1

ANSWER

pls see in pic

in this famous equation

e is energy 

m is mass

and c ^2 is speed of light

using this equation 

Einstein showed the relationship between the mass and energy.

and according to the theory of relativity

nothing can travel higher than the speed of light.

which values 299729458m/s

THANKS

Answer 2

$\huge\mathfrak{Good\: Morning\: Mate}$

$\huge\bold{Einstein\: Equation}$

let F=ma ....... 1

we know that a = v/t

where v is the velocity.....

and F = e/d

where d is the distance....

put these values in equation 1

e/d = m*v/t

or e = m*v*d/t ........ 2

since we know that d/t = v put this value in equation 2

therefore we have e = m*v*v

or e= mv^2

if particle is a electron.....

then take v=c ( i.e. speed of light )

so e = mc^2

Hope it helps you Out✌✌
