Question

3:

Answer 1

M=e/c2

U just divide e=mc2 by c2 on both sides to isolate m

Answer 2

Answer:

$E=m.c^2\\m=\frac{E}{c^2}$

Step-by-step explanation:

If we have the values of E (energy) and c (speed of light) to obtain an equation that gives us the value of m (mass of the object), we clear the variable m from the initial equation

$E=m.c^2\\m=\frac{E}{c^2}$
