im stuck with this problem:
the question asked for the gravatational force of attraction between moon and Earth while the moon's radius is not given.
do i need the moon's radius? since r is the distance from the center of moon to the center of Earth (right?) and the second question of the same question is that i have to find the Earth's gravitational field at the moon. so if i use GM/r=g, same, moon's radius is not given, so then i cannot calculate it??
my physics sucks a lot, so please help~
