A satellite revolves close to the surface of a planet. How is its orbital velocity related with escape velocity of that planet.

Explanation

To find the relationship between the orbital velocity of a satellite revolving close to the surface of a planet and the escape velocity of that planet, we can follow these steps:

### Step 1: Define Escape Velocity
The escape velocity (\(V_e\)) is the minimum velocity required for an object to escape the gravitational pull of a planet without any further propulsion. It can be derived from the conservation of energy principle, where the kinetic energy of the object is equal to the gravitational potential energy.

The formula for escape velocity is given by:
\[
V_e = \sqrt{\frac{2GM}{R}}
