Question

Astrology Nonsense 1 point Astrology makes a big deal about the position, and thus gravitational pull, of the planets at the moment of a person's birth. Suppose a 4.0 kg baby is born to 100 kg mother and a 100 kg father. What is the gravitational force of Mars on the baby when it is at its closest approach, at a distance of about 57.6 million km? Mars has a mass of 6.41 x 104 kg. Just give the exponent of your answer. Don't round it before you report the exponent. Type your answer... 1 point Now let's calculate the force of the mother on the baby as she is holding it. Suppose that the center of mass of the mother is 0.2 m away from the center of mass of the baby. Again, just report the exponent of your answer, and don't round anything. Type your answer... 10 1 point What is gravitational force of the father on the baby as he sits on a chair 10 m away? Again, just report the exponent. Type your answer...

Answer 1

Here we apply Newton's law of gravitation.

Newton's law of Gravitation force between A two masses is always cettractive of as given by ir mima To Here r= Seperation between them G = Gravitational Constant.
