Question

An astrologer claims that the position of Saturn in the sky has a strong influence on human life, so you decide to calculate whether Saturn could possibly exert a significant gravitational effect on humans on Earth. Find a. the gravitational force of Saturn on your body, and for comparison, b. the gravitational force of a friend sitting next to you. The mass of Saturn is a well-measured astronomical value - please look it up. The distance between you and Saturn varies within a limited range - you can use any value within this range. For all other masses and distances, you can choose any REALISTIC values, given the context of the question. Before you calculate, list your chosen values here, including units and appropriate significant figures: mass of you: _____distance between centers of you and Saturn: _____ mass of friend: _____ distance between centers of you and friend: _____ Now, find the answer to the initial question. Show your work completely (including rewriting any of the above values in the course of your calculations):

Explanation / Answer

mass of saturn Ms = 5.683*10^26 kg

distance between earth and saturn r1 = 1.2*10^12 m

gravitational force F = G*m*Ms/r1^2 = 6.7*10^-11*75*5.683*10^26/(1.2*10^12)^2

F = 1.98*10^-6 N
