Physics

Astrology, that unlikely and vague pseudoscience, makes much of the position of the planets at the moment of one’s birth. The only known force a planet exerts on objects on Earth is gravitational. (a) Calculate the gravitational force exerted on a
4.20 kg baby by the Earth. (b) Calculate the force on the baby due to Jupiter when it is
6.29×1011 m away, its closest approach to Earth. Food for thought: how does the force of Jupiter on the baby compare to the force of the Earth on the baby?
