Question

A planet is orbiting the sun in an elliptical orbit. Let $U$ denote the potential energy and $K$ denote the kinetic energy of the planet at an arbitrary point on the orbit. Choose the correct statement.

• A. $K<\left|U\right|$ always
• B. $K>\left|U\right|$ always
• C. $K=\left|U\right|$ always
• D. $K=\left|U\right|$ for two positions of the planet in the orbit

Answer 1

The correct option is A $K<\left|U\right|$ always

Since the total energy is equal to maximum potential energy ,U will get converted to K partially ,U is always greater than K
