The distance of a direct broadcasting satellite from earth's surface is about

A satellite of mass m is revolving round the Earth at a height R above the surface of the Earth. If g is the gravitational intensity at the earth surface and R is the radius of the Earth, then the kin

An artificial satellite is moving in a circular orbit around the Earth with a speed equal to half the magnitude of escape velocity from the Earth. The height of satellite above the surface of Earth is

Two satellite move in circular orbits around the Earth at distance 9000 km and from the centre of Earth. If the nearer satellite has a period of revolution of 90 minutes around the Earth, then the dif

The direct distance between City A and City B is 300 miles. The direct distance between city B and City C is 400 miles. What could be the direct distance between city C and City A

If an artificial satellite is moving in a circular orbit around the earth with a speed equal to half the magnitude of the escape velocity from the earth, the height of the satellite above the surface

Assume that the time period of a satellite close to the surface of Earth is 80 minutes. What is the time period of another Earth satellite in an orbit of radius equal to four times the Earth s radius

A research satellite of mass 200 kg circles the Earth in an orbit of average radius 3R/2, where R is the radius of the Earth. Assuming the gravitational pull on a mass 1 kg on Earth s surface to be 10

A satellite is launched in a circular orbit of radius R and another satellite is launched in circular orbit of radius 1.01 R. The time period of second satellite is different from that of the first sa

A satellite of mass m is revolving at a height R above the surface of Earth. Here R is the radius of the Earth. Th gravitational potential energy of this satellite is
