Question

Figure shows the orbit of a planet P round the sun S. AB and CD are the minor and major axes of the ellipse.


If U is the potential energy and K kinetic energy then $|U|>|K|$ at

• A. Only D
• B. Only C
• C. Both D & C
• D. Neither D nor C

Answer 1

The correct option is C Both D & C

Total energy of planet at any point $=–\frac{GMm}{2a}$.
So at every point potential energy will be greater than kinetic energy.
