A rocket is fired from the earth to the moon. The distance between the earth and the moon is r and the mass of the earth is 81 times the mass of the moon. The gravitational force on the rocket will be zero when its distance from the moon is

There is a point between the earth and the moon, where the gravitational force on a space ship due to earth and moon together is zero. Find the distance of that point from the earth Given the disatnce between earth and moon is 3.845 x 10^(8) m and the moon has 1.2 % of the mass of the earth.

A space-ship is launched into a circular orbit close to the Earth,s surface. What additional speed should now be imparted to the spaceship so that it overcome the gravitational pull of the Earth. Take kinetic energy of the space-ship, K = total energy of space-ship = (GMm)/(2R) where m = mass of space-ship, M= mass of the earth and R = radius of the earth.

If g is the acceleration due to gravity and R is radius of earth, the minimum kinetic energy required to make a satellite to move to infinity from orbit which is close to earth is

The ratio of the kinetic energy required to be given to a satellite to escape from the earths gravity to the kinetic energy required to be given to it so that it moves in a circular orbit just above the eart's surface is:
