An artificial satellite completes a circle around earth in 120 minutes. Calculate the height of the satellite above the earth's surface.
Take, radius of earth = 6,400 km
`g = 9.8 m//s^(2)`

Explanation

To solve the problem of finding the height of an artificial satellite above the Earth's surface, we can follow these steps:

### Step 1: Convert the time period from minutes to seconds
The time period \( T \) is given as 120 minutes. We need to convert this to seconds:
\[ T = 120 \text{ minutes} \times 60 \text{ seconds/minute} = 7200 \text{ seconds} \]
