Q. The correct graph representing the variation of total energy $(E)$ kinetic energy $(K)$ and potential energy $(U)$ of a satellite with its distance from the centre of earth is
A)
B)
C)
D)
Explanation
(c) $U = \frac{- GMm}{r},\ K = \frac{GMm}{2r}$ and $E = \frac{- GMm}{2r}$
For a satellite $U,K$ and $E$ varies with $r$ and also $U$ and $E$ remains negative whereas $K$ remain always positive
