## Homework Statement

its 3.8 x 10^8 from Earth's core to the lunar's core

calculate the gravitational attraction exerted by Earth on the moon

## Homework Equations

ag = GM/ r^2

G= 6.67 x 10^-11

M of earth= 5.98 x 10^24 ... r= 6.37 x 10^6

M of moon= 7.36 x 10^22 ... r= 1.74 X 10^6

## The Attempt at a Solution

ag = ( 6.67 x 10^-11)( 7.36 x 10^22) / ( 6.37 x 10^6) ^2 = 0.12 N

I'm not sure if I'm right or not, I am just really confused as to where I plug in the numbers
