Question Details
Answer the problems, pay attention to units.

1. Calculate the force between two objects that have masses of 70kg and 2,000 kilograms separated by a distance of 1 meter.

2. Calculate the force between two touching grapefruits each with aradius of 0.08 meters and a mass of 0.45 kilograms.

3. Calculate the force between one grapefruit as described aboveand EArth. EArth has a mass of 5.9742 x10^24 kg and a radius of6.3710 x 10^6 meters. Assume the grapefruit is resting on Earth'ssurface.

The gravitational force F between two bodies of masses m1 and m2

 

where G is the gravitational constant (6.672 × 10−11 N m2 / kg2), m1 and m2 are the masses of the bodies in kilograms, and r is the distance between the two bodies. Write a function to calculate the gravitational force between two bodies given their masses and the distance between them. Test your function by determining the force on an 800 kg satellite in orbit 38,000 km above the Earth. (The mass of the Earth is 6.98 × 1024 kg and the radius of the Earth is 6.371 × 106 m.)

This is problem 12.9 inUniversity Physics 12ed
This refers to the attached image, but only to the middle portionlabeled (b)
G=6.67*10^(-11)
Mass of Moon=7.35*10^22 kg
Mass of Earth=5.97*10^24 kg
Mass of Sun=1.99*10^30 kg
Radius from center of moon to center of earth inmeters=3.84*10^8
Radius from center of earth to center of sun inmeters=1.5*10^11
I need to find the net gravitational force in magnitude anddirection on the moon due to the earth and the sun. The solutionsmanual does not show any work that is helpful in this problem. Theycome up with the Fg of Earth/Moon as 1.99*10^20 then the Fg ofSun/Moon as 4.34*10^20 yet the final answer is 4.77*10^20. Lastly they somehow calculate without showing that it's directionis 24.6 degrees directed towards the sun. I'm just lost on thisproblem.

Thanks!
