The orbital speed for an earth satellite near the surface of the earth is 7km//sec . If the radius of the orbit is 4 times the radius of the earth, the orbital speed would be

The orbital velocity of a satellite very near to the surface of earth is v. What will be its orbital velocity at an altitude 7 times the radius of the earth?

The period of revolution of an earth satellite close to surface of earth is 90min. The time period of aother satellite in an orbit at a distance of three times the radius of earth from its surface will be

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

The escape velocity of a body from the surface of the earth is 11.2 km/s. If a satellite were to orbit close to the surface, what would be its critical velocity ?

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

The orbital velocity of an satellite in a circular orbit just above the earth's surface is v . For a satellite orbiting at an altitude of half of the earth's radius, the orbital velocity is
