Please help me with this (relatively) simple question.
Experiment 1: I use laser method to measure distance from my particular location on the surface of Earth to the Moon. The distance I got is D. I note that while laser light was traveling to the Moon and back it was traveling under influence of Earth's gravitation.
Experiment 2: With all other parameters unchanged (like bodies locations etc), Earth suddenly lost half of its mass. The loss of mass was sudden and the Moon had no time to adjust its orbit, so everything else is the same except Earth's mass. Now I make measurement again. The distance I got is D1.
Earth's mass lower - gravitation lower - clocks tick faster. Will I see D1 smaller than D or the opposite? Which formula can I use to calculate the difference?
Thank you.
