An artificial satellite is revolving around the earth in a circular orbit. Its velocity is one-third of the escape velocity. Its height from the earth's surface is (in `km`)

A satellite revolves around the earth in an elliptical orbit. Its speed is

Two satellites P,Q are revolving around the earth in different circular orbits. The velocity of P is twice the velocity of Q . The height of P from the earth's surface is 1600 km . The radius of orbit of Q is (R=6400 km)

An artificial satellite revolves around the Earth with a constant velocity. It’s the statement true ?

An artificial satellite is moving in a circular orbit around the earth, with a speed which is equal to half the magnitude of the escape velocity from the earth. What is the height of the satellite above the surface of the earth ?

A satellite is revolving around the earth. Ratio of its orbital speed and escape speed will be.

A small satellite is revolving near earth's surface. Its orbital velocity will be nearly
