A satellite is revolving round the earth at a height of 600 km. find a. The speed of the satellite and b. The time period of the satellite. Radius of the earth =6400 km and mass of the earth `=6xx10^24kg`.

Explanation

To solve the problem, we need to find the speed of the satellite and the time period of its revolution around the Earth.

### Given Data:
- Height of the satellite (h) = 600 km = 600,000 m
- Radius of the Earth (R) = 6400 km = 6,400,000 m
- Mass of the Earth (M) = \(6 \times 10^{24}\) kg
- Gravitational constant (G) = \(6.67 \times 10^{-11} \, \text{N m}^2/\text{kg}^2\)
