Gravitational force = G M1 M2/ d^2
G = 6.67 * 10^-11 kg^2 N^-1 m^-2
M1 = 5.98 * 10^24 kg
M2 = 7.3 * 10^22 kg
d = 3.93 * 10^8 m
Plugging you can get the force = 18.85 * 10^19 N

∙ 14y agoYou said that Ellen is an Earthling, but you have not said that she is on the earth as this measurement is made. For purposes of the computation, we boldly make that assumption.
F = G M1M2/R2
G = 6.67 x 10-11
M1 = 7.35 x 1022
M2 = 47
R = 3.84 x 108
F = (6.67 x 10-11) (7.35 x 1022) (47) / (3.84 x 108)2
= (6.67 x 7.35 x 47) / (3.84)2 x 10-11+22-16
= 156.26 x 10-5 = 0.0015626 Newton = 0.00564 ounce (rounded)
