Calculate the force of gravity between a newborn baby (mass = 2.6 kg) and the planet Mars (mass = 6.4 * 10^23kg) when Mars is at its closest to Earth (distance = 5.6 * 10^10m).

Answer 1

G*M1*M2/d^2
M1 and M2 are the two masses.
d = 5.6*10^10 m
G = 6.67*10^-11 N*m^2/kg^2
Do the numbers for the attraction force in newtons

Answer 2

Yes. It should be in Newtons. :)

Answer 3

5.6
