An astronaut orbiting the earth in a circular orbit `120km` above the surface of earth, gently drops a spoon out of space-ship. The spoon will

An astronaut orbiting the earth in a circular orbit 120km above the surface of earth, gently drops a ball from the space-ship. The ball will

A satellite is orbiting the earth in a circular orbit of radius r . Its

A satellite is revolving round the earth in circular orbit

A satellite ils launched into a circular orbit 1600km above the surface of the earth. Find the period of revolution if the radius of the earth is R=6400km and the acceleration due to gravity is 9.8ms^(-2) . At what height from the ground should it be launched so that it may appear stationary over a point on the earth's equator?

An artificial satellite is revolving in a circular orbit at height of 1200 km above the surface of the earth. If the radius of the earth is 6400 km and mass is 6xx10^(24) kg , the orbital velocity is

A remote sensing satellite of the Earth in a circular orbit at a height of 400 km above the surface of Earth. What is the (a) orbital speed, and (b) period of revolution of satellite ? Radius of Earth = 6 xx 10^(6) m and acceleration due to gravity the surface of Earth is 10 m//s^(2) .

Two satellite revolve around the earth in circular orbits at heights h_(1) and h_(2) above the surface of the earth respectively. If R is radius of the earth, then the ratio of their orbital linear velocities is

A satellite of mass 10 kg is placed initially in a temporary orbit 800 km above the surface of earth. The satellite is to be placed now in a permanent orbit at 2000 km above the surface of earth. Find the amount of workdone to move the satellite from temporary to permanent orbit. The radius of the earth is 6400 km and g = 10 ms^(-2) .
