A satellite is revolving round the earth at a height of 600 km. find a. the speed f the satelite and b. the time period of thesatellit. 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 its time period. Let's break it down step by step.

### 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) = \(6.67 \times 10^{-11} \, \text{N m}^2/\text{kg}^2\)
