Father’s gravitational force on the baby is:

Jupiter’s gravitational force on the baby is:

**(c)** What should be the father’s weight, so that he exerts the same force on the baby as that of Jupiter? *****this section is not included in the Reference material*

Discussion

Other 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.)Reference : OpenStax College,College 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 Earth is gravitational.

(a)Calculate the gravitational force exerted on a4.20 kgbaby by a100 kgfather0.200 maway at birth (he is assisting, so he is close to the child).(b)Calculate the force on the baby due to Jupiter if it is at its closest distance to Earth, some6.29e+11 maway. How does the force of Jupiter on the baby compare to the force of the father on the baby?
