Q 11-07-108JEE MainJEE Main 2023 (8 Apr, Shift 1)Easy
Given below are two statements:
**Statement I:** If $E$ be the total energy of a satellite moving around the earth, then its potential energy will be $\dfrac E2$.
**Statement II:** The kinetic energy of a satellite revolving in an orbit is equal to the half the magnitude of total energy $E$.
In the light of the above statements, choose the most appropriate answer from the options given below.
Answer: (D) Both Statement I and Statement II are incorrect
For a circular orbit $E=-\dfrac{GMm}{2r}$, $U=-\dfrac{GMm}{r}=2E$ and $K=\dfrac{GMm}{2r}=|E|$. Both statements are incorrect.
