A 30 kg satellite has a circular orbit with a period of 2.0 h and a radius of `9.0 xx 10^6` m around a planet of unknown mass. If the magnitude of the gravitational acceleration on the surface of the planet is `6.0 m//s_2`. what is the radius of the planet?

Explanation

To find the radius of the planet given the parameters of the satellite, we can follow these steps:

### Step 1: Identify the given values
- Mass of the satellite (m) = 30 kg (not needed for calculations)
- Period of the satellite (T) = 2.0 hours = 2 × 60 × 60 seconds = 7200 seconds
- Radius of the satellite's orbit (r) = \(9.0 \times 10^6\) m
- Gravitational acceleration on the surface of the planet (g) = 6.0 m/s²
