Q: Mike was reading about an instrument that could measure gravity, gravimeter. He then found how gravimeter was used to measure the gravitational field of the Moon. He read about two distinct cases where the Moon's gravitational field was measured on earth, side A and side B. In side A the Moon's gravity was measured from the side where the Earth was facing the Moon. And in side B the Moon's gravitational field was measured from the opposite side of the Earth. He found these two locations showed very different consequences of Moon's gravitational field. On which side the Moon's gravitational field would exert stronger force, side A side B?
A: side A
