Answer 1

Answer:

$M_{2}=\frac{F_{g}r^{2}}{GM_{1}}$

Step-by-step explanation:

To find $M_{2}$, you can manipulate the formula.

$F_{g}=\frac{GM_{1}M_{2}}{r^{2}}$ (given)

$F_{g}r^{2}=GM_{1}M_{2}$  (times r² on both sides)

$M_{2} = \frac{F_{g}r^{2}}{GM_{1}}$  (divide both sides by $GM_{1}$)

∴ $M_{2}=\frac{F_{g}r^{2}}{GM_{1}}$ in terms of $F_{g}, G, M_{1}$ and $r$
