The moon has a mass of 7.35 *10^22 kg and is located 3.84*10^8 m from the earth. if Ellen, an earthling, has a mass of 47 kg, what is the gravitational force between Ellen and the moon?

Question

anonymous · Answer

$$F=\frac{ GM _{1} M _{2}}{ r ^{2} }$$ where F is the gravitational force, 
G the universal gravitation constant $$6.67\times10^{-11}Nm^{2}/kg^{2}$$M1 is the mass of ellen$$47 kg$$M2 is the mass of the moon and$$7.35\times10^{22}kg$$r is the distance between ellen and the moon, which is the same as the distance from the moon and the earth
$$3.84\times10^{8}m$$
$$F = 1.56\times10^{-3}N$$
