An object weighs 100N on the earth's surface. Find its weight at a point P with orbital radius 2R. [g =

10NKg-1

1 answer

G = universal gravitational constant

F = G Me m/r^2

G Me and m do not change
so
F' = G Me m /(2r)^2 = G Me m /4r^2

so
100/4
= 25 N

(assuming it has no velocity, like not in orbit :)
