Question

1.The escape velocity on the surface of earth is 11km/s .What is the escape velocity at the height of 0.5R from the surface of the Earth?

2.What is the orbital speed of a satellite which is at a higher of 2R from the surface of the Earth?​

Answer 1

Explanation:

The escape velocity on the surface of earth is 11km/s .What is the escape velocity at the height of 0.5R from the surface of the Earth?

2.What is the orbital speed of a satellite which is at a higher of 2R from the surface of the Earth

the escape velocity of a body of mass 1 kg from the earth surface is 11.2 km per second escape velocity for a body of mass 100 kg would be
