Question

As the distance of the planet from the sun increases, the period of revolution decreases.

• A. True
• B. False

Answer 1

The correct option is B False

Kepler's third law of planetary motion states that the square of the orbital period of a planet is proportional to the cube of the semi-major axisof its orbit.

Now as the distance of the planet from the sun increases, the length of the semi-major axis of its orbit will also increase and therefore the period of revolution will also increase.

Hence the given statement is $False$ and correct option is $B$
