Can someone help me with these gravitational force problems? Thanks!
(a) Calculate the gravitational force exerted on a 4.20 kg baby by a 100 kg father 0.200 m away at birth (assisting, so he is close).
(b) Calculate the force on the baby due to Jupiter if it is at its closest to the Earth, some 6.29x1011 m away, showing it to be comparable to that of the father. Other people and objects in the room and the hospital building also exert similar gravitational forces. (Of course, there could be an unknown force acting, but scientists first need to be convinced that there is even an effect, much less that an unknown force causes it.)
