What it Einstein's mass energy relation?

Text Solution

Verified by Experts

Let `m_(0)` =Rest mass of a particle K.E. of moving particle = `c^(2)` (Increase in mass due to motion of particle)
`=c^(2)(m-m_(0))`
`=mc^(2)-m_(0)c^(2)`
Rest mass energy of a particle `=m_(0)c^(2)`
Total energy of a moving particle `E=(mc^(2)-m_(0)c^(2))+m_(0)c^(2)`
`E=mC^(2)`
Which is the required mass energy relationship.
