force between them is 0.0104 N, find the mass of each object.

Answer 1

Explanations & Calculations

$\qquad\qquad \begin{aligned} \small F&=\small G\frac{m\times m}{r^2}\\ \small m&=\small r\sqrt{\frac{F}{G}}\\ &=\small 0.002\sqrt{\frac{0.0104N}{6.67\times10^{-11}m^3kg^{-1}s^{-2}}}\\ &=\small 24.97kg\\ &\approx\small 25kg \end{aligned}$
