1)determine the hieght h above the surface where the value of g falls to 1 % of the value at the surface.

2)taking moon's period of revolution about the earth as 30 days . calculate its distance from the earth .( mass of earth = 6 x 10^24 kg )

plzzz answer ,xperts !!

a particle of mass m1 is kept at x = 0 and another of mass m2 at x =d. when a third particle is kept at x= d/4, it xperiences no net gravitional force due to the two particles . find m1 / m2
