Newton's Law of Universal Gravitation Relates the Force $F$ With Which a Particle of Mass

Newton's Law of universal gravitation relates the force $F$ with which a particle of mass $m_{1}$ attracts a particle of mass $\mathrm{m}_{2}$ to the gravitational constant $\mathrm{G}$ and the distance $r$ between the two objects: $\mathrm{F}=\frac{\mathrm{Gm} 1 \mathrm{~m} 2}{\mathrm{r}^{2}}$ . Solve this equation for $\mathrm{G}$ .

A) $\mathrm{G}=\frac{\mathrm{Fr}^{2}}{\mathrm{~m}_{1} \mathrm{~m}_{2}}$

B) $G=\frac{r^{2} m_{1}}{F m 2}$

C) $\mathrm{G}=\frac{\mathrm{Fm} 1}{\mathrm{r}^{2} \mathrm{~m}_{2}}$

D) $\mathrm{G}=\frac{\mathrm{m}_{1} \mathrm{~m}_{2}}{\mathrm{Fr}^{2}}$
