Balance gravitationattraction between the earth and moon

Reference no: EM13554061

Suppose a charge +Q is placed on Earth, and another charge +Q isplaced on the Moon.

a) Find the value of Q needed to "balance" the gravitationattraction between the Earth and the Moon.
b) How would your answer to part (a) change if the distancebetween the Earth and the Moon were doubled? Explain.
