Question

How does the time period of revolution vary with the distance of the planet from the Sun?

• A. Greater the distance, lesser the time period
• B. Greater the distance, greater the time period
• C. The time period of revolution is independent of the distance from the sun
• D. The sum of time period and the distance from the sun is constant.

Answer 1

The correct option is B Greater the distance, greater the time period

A planet has a definite path in which it revolves around the Sun. This path is called an orbit. The period of revolution of a planet around the Sun increases as the distance of the planet increases from the Sun. Hence, greater the distance, greater is the time period.
