Hey:

I am trying to solve this problem, but getting nowhere, any help would be greatly appreciated!

What is the net gravitational force exerted on a 3.00 X 10^4 kg spaceship halfway between the Earth and the Moon. The average distance between the Earth and the Moon is 384,000 km. The Earth's mass is 5.98 X 10^24 kg, and the Moon's mass is 7.36 X 10^22 kg.

I am confused.

Thanks!
