Can someone plz help me I wanna go to sleepppppp!!

Answer 1

`M_(2)=(F_(g)r^(2))/(GM_(1))`

Explanation:

To find
`M_(2)`, you can manipulate the formula.

`F_(g)=(GM_(1)M_(2))/(r^(2))` (given)

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

`M_(2) = (F_(g)r^(2))/(GM_(1))` (divide both sides by
`GM_(1)`)

∴
`M_(2)=(F_(g)r^(2))/(GM_(1))` in terms of
`F_(g), G, M_(1)` and
`r`
