A `10kg` satellite circles earth once every `2hr` in an orbit having a radius of `8000km`. Assuming that Bohr's angular momentum postulate applies to satellites just as it does to an electron in the hydrogen atom, find the quantum number of the orbit of the satellite.

Explanation

To find the quantum number of the orbit of a satellite using Bohr's angular momentum postulate, we can follow these steps:

### Step 1: Convert the given time into seconds
The satellite takes 2 hours to complete one orbit. We need to convert this time into seconds.

\[ \text{Time} = 2 \text{ hours} = 2 \times 60 \times 60 = 7200 \text{ seconds} \]
