Question

Which of following relations is correct for Einstein-mass energy relation?

• A.
  $E=\Delta m{c}^2$
• B.
  $E=\Delta m^{2}c$
• C.
  $E=\Delta mc$
• D.
  $\Delta m$

Answer 1

The correct option is A

$E=\Delta m{c}^2$
Einstein mass-energy relation is given as, $E=\Delta m{c}^2$

Here, $\Delta m$ = change in mass and c = speed of light

Hence, the correct answer is option (a).
