Astrology, that unlikely and vague pseudoscience, makes much of the position of the planets at the moment of ones birth. the only known force that a planet could exerts on us is gravitational, so if there is anything to astrology we should expect this force to be significant.Calculate the magnitude of the gravitational force (in N) exerted on a 3.00 kg baby by a 110 kg father 0.150 m away at birth (he is assisting, so he is close to the child.)
