The gravitational force between a 4.9 kg backpack and a second backpack of unknown
mass is 3.74*10^-10N The distance between the centers of the backpacks is 2.5 M -
answer7.2 kg
The gravitational force between a pair of identical twins who each have a mass of 75.6
kg is 6.126*10^-10 N - answer24.9M
Suppose that in some far away solar system, there are two planets in the same circular
orbit around a central star. The two planets have the same mass, but planet 2 is larger
in size. Let Fp1 be the force between the star and planet 1, and Fp2 be the force
between the star and planet 2. - answerFp1=Fp2
A 1,500 kg satellite is in orbit around the Moon at a distance of 3 Moon radii above the
surface of the Moon. The Moon's mass is 7.35*10^22 and its radius is 1.74*10^6 M -
answer152 N
Two coins, made of different material, are placed next to each other so that they are
touching. Both coins are 15mm in diameter. One coin has a mass of 6.5g and the
gravitational force between the coins is 4.03*10^-11 N - answer21g
The gravitational force between a 105kg person and the 5.97*10^24 kg Earth is 1,030
kg - answer6.37*10^6 m
Suppose that in some far away solar system, there are two planets in the same circular
orbit around a central star. The two planets have the same mass, but planet 2 is larger.
An alien lands on planet 1 and then on planet 2. Let Wp1 be the weight of the alien on
planet 1 and Wp2 be the weight of the alien on planet - answerWp1>Wp2
A 1,500 satellite is in orbit around Earth at a distance of 1 Earth radius above the
surface.
Earth's mass is 5.97*10^24 kg, and its radius is 6.37*10^6 m - answer3,700 N
