Select the correct statement from the following

1. The orbital velocity of a satellite increases with the radius of the orbit
2. Escape velocity of a particle from the surface of the earth depends on the speed with which it is fired
3. The time period of a satellite does not depend on the radius of the orbit
4. The orbital velocity is inversely proportional to the square root of the radius of the orbit

Correct answer: The orbital velocity is inversely proportional to the square root of the radius of the orbit
