1. The problem statement, all variables and given/known data People who believe in astrology think the positions of the planets at the time of birth have a large effect on the personality and destiny of the baby. The only known interaction between a planet and the baby is the force of gravity. Calculate the force of gravity (in Newtons) between a newborn baby (mass = 4.5 kg) and the planet Mars (mass = 6.4 X 1023 kg), when Mars is at its closest to the Earth (distance = 5.6 X 1010 m). Calculate the force of gravity (in Newtons) between a newborn baby of mass 4.5 kg and the obstetrician of mass 100 kg, who is 0.5 m from the baby. 2. Relevant equations 3. The attempt at a solution Fg= g ( 4.50 kg)(100.0 kg)/0.5m^2 =Fg= (6.67 E -11 N*m2/kg2)( 4.50 kg)(100.00 kg)/0.5m^2 I arrive at -1.32E4 but it gives me incorrect answer. I am completely lost with this problem.
