Which has longer period of revolution, a satellite revolving close or away from the surface of earth?

Explanation

To determine which satellite has a longer period of revolution—one revolving close to the surface of the Earth or one revolving farther away—we can analyze the relationship between the gravitational force, centripetal acceleration, and the period of revolution.

### Step-by-Step Solution:

1. **Understanding the Forces**:
The gravitational force acting on the satellite provides the necessary centripetal force for its circular motion. The gravitational force \( F_g \) can be expressed as:
\[
F_g = \frac{G M m}{(R + h)^2}
