A body is orbitting around the earth at mean radius `9` times as great as the orbit of a geostationary satellite to how many days it will complete one revolution around the earth and what is its angular velocity ?

Explanation

To solve the problem, we need to determine the time period of a body orbiting the Earth at a mean radius that is 9 times the radius of a geostationary satellite, and then calculate its angular velocity.

### Step-by-Step Solution:

1. **Identify the Mean Radius of the Geostationary Satellite**:
- Let the mean radius of the geostationary satellite be \( R_1 \).
- The mean radius of the body in question is \( R_2 = 9R_1 \).
