The figure shows the revolution of the planet (P) around the sun (S) in an elliptical orbit. Which of the following statements is true regarding time taken?

A planet revolves around the Sun in an elliptical orbit. The areal velocity of the planet is \(4 \times 10^{16}\,\text{m}^2\text{s}^{-1}\). If the maximum distance between the planet and the Sun is \(4 \times 10^{12}\,\text{m}\), then the minimum speed of the planet is:

A planet revolves around the sun in an elliptical orbit. The areal velocity is 4 10^16 m^2s^-1. Maximum distance is 4 10^12 m. Find minimum speed.

A satellite P takes 2 years to make a circular orbit of radius R around the earth. The time period of another satellite Q if it moves in a circular orbit twice the orbital radius of satellite P around earth is:

Two planets, A and B orbit around a star such that the time period of A is 8 times the time period of B. The ratio of orbital velocities of the planets A and B is:

A satellite is revolving in a circular orbit around the earth with a speed of 8.4 km s\(^{-1}\) at a height where the acceleration due to gravity is 8.4 m s\(^{-2}\). The height of the satellite from the Earth's surface is (Radius of Earth = 6400 km)

Assume a planet with orbiting radius R and period of revolution T around the sun experiences a gravitational force which follows inverse cube law instead of inverse square law. In this case, the period of revolution is proportional to:
