Some people believe that the positions of the planets at the time of birth influence the newborn. Others deride this belief and claim that the gravitational force exerted on a baby by the obstetrician is greater than the force exerted by the planets. To check this claim, calculate the magnitude of the gravitational force exerted on a 3 kg baby

(a) By a70 kg obstetrician who is 1 m away and roughly approximated as a point mass,

(b) By the massive planet Jupiter (m = 2 x 1027 kg) at its closest approach to Earth (= 6 x 1011 M), and

(c) By Jupiter at its greatest distance from Earth (= 9 x 1011 m).

(d) Is the claim correct?
