A planet goes around the sun in an elliptical orbit. The minimum distance of the planet from the Sun is ` 2xx10^(12)m` and the maximum speed of the planet in its path is `40kms^(-1).` Find the rate at which its position vector relative to the sun sweeps area, when the planet is at a distance `2.2xx10^(12)` from the sun.
