During a solar eclipse the Moon is positioned directly between Earth and the Sun. Find the magnitude of the net gravitational force acting on the Moon then, due to both Earth and the Sun. The masses of the Sun, Earth, and the Moon are 1.99 x100 kg, 5.98 x1024 kg, and 7.36 x 1022 kg, respectively. The Moon's mean distance from Earth is 3.84 × 108 m, and Earth's mean distance from the Sun is 1.50 x 1011 m. The...

How far above the surface of the Earth will a person’s weight be reduced to one-quarter its value at the surface? g=Gme/r2 where me is the mass of the Earth, r is the distance from the Earth’s center to the height above Earth and G is the proportionality constant. You will need to look up the mass and radius of the Earth.

How far above the surface of the Earth will a person’s weight be reduced to one-quarter its value at the surface? Hint: g=Gme/r2 where me is the mass of the Earth, r is the distance from the Earth’s center to the height above Earth and G is the proportionality constant. You will need to look up the mass and radius of the Earth.
