Problem 3 As you travel from the Earth to the Moon, you must reach a point where the gravitational pull of the Moon is equal in magnitude, but opposite to, the gravitational pull of the Earth. How far from the center of the Earth is that point, and how strong is the Earth's pull there, compared to how strong it is at the Earth's surface? (Take the center of the Moon to be a distance of 3.844 ! 10^8m from the center of the Earth. The mass of the Earth is 5.97 ! 10^24kg; the mass of the Moon was given in the previous problem!)

Step 1
We need to find the distance from the Earth's center where the gravitational pull from the Earth equals the gravitational pull from the Moon. We also need to compare the Earth's gravitational pull at this point to its pull at the Earth's surface. Show moreā¦

The moon is 3.9 Ć 10^5 km from the center of the earth. The mass of the moon is 7.3 Ć 10^22 kg, and the mass of the earth is 6.0 Ć 10^24 kg. How far from the earth's center are the gravitational forces on an object due to the earth and moon equal and opposite? (Assume the object is on the line connecting the earth and moon.)
