Question

Astrology, that unlikely and vague pseudoscience, makes much of the position of the planets at the moment of oneâs 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.

Required:

a. Calculate the gravitational force, in Newtons, exerted on aÂ 4.1Â kgÂ baby by aÂ 120Â kgÂ father who is a distance ofÂ 0.18Â mÂ away at the time of its birth.

b. Calculate the force on the baby, in Newtons, due to Jupiter (the largest planet, which has a mass ofÂ 1.90Ã10^27Â kg if it is at its closest distance to Earth,Â 6.29Ã10^11Â mÂ away.

c. What is the ratio of the force of the father on the baby to the force of Jupiter on the baby?

## Answers ( )

Answer:Explanation:Gravitational force between two objects having mass m₁ and m₂ at a distance R

F = G m₁ m₂ / R²

Force between baby and father F₁ = 6.67×10⁻¹¹ x 4.1 x 120 / .18²

= 1.01 x 10⁻⁶ N

b )

Force between baby and Jupiter

F₂ = 6.67×10⁻¹¹ x 1.9x 10²⁷ x 4.1 / ( 6.29 x 10¹¹ )²

= 1.31 x 10⁻⁶ N

c )

Ratio = 1.01 / 1.31

= .77
