Two artificial satellites one close to the surface and the other away, are revolving around the earth. Which one has larger speed?

Explanation

To determine which of the two artificial satellites, one close to the surface of the Earth and the other further away, has a larger speed, we can analyze the orbital velocity of satellites based on their distance from the center of the Earth.

### Step-by-Step Solution:

1. **Understanding Gravitational Force and Centripetal Acceleration**:
- The gravitational force acting on a satellite is given by the formula:
\[
F = \frac{G \cdot M \cdot m}{r^2}
