A small satellite revolves around a planet in an orbit just above planet's surface. Taking the mean density of the planet `8000 kg m^(-3)` and `G = 6.67 xx 10^(-11) N //kg^(-2)`, find the time period of the satellite.

Explanation

To find the time period of a small satellite revolving around a planet just above its surface, we can follow these steps:

### Step 1: Understand the formula for the time period of a satellite
The time period \( T \) of a satellite in orbit can be expressed using the formula:
\[ T = 2\pi \sqrt{\frac{r^3}{GM}} \]
where:
