1. The problem statement, all variables and given/known data
The question is: What is the distance between the moon and the earth if the mass of the moon is 7.34 x 10(to the power of 22) kg and the force of attraction between the two is 2.00 x 10(to the power of 20) N?
Mass of the moon = 7.34 x 10(to the power of 22) kg
Attraction = 2.00 x 10(to the power of 20) N
Gravitional constant = -6.67 x 10(to the power of -11) N.m(squared)/kg(squared)
Mass of the earth = ?
Distance between earth and moon = ?
2. Relevant equations
F = G x m1 x m2
r(squared)
3. The attempt at a solution
First, im pretty sure that i first need to find the mass of the earth. After, i will be able to sub in all the information to get the answer. I just need help to find the mass of the earth. Please help me.
