An artificial satellite is made to move in circular orbits of different radii around the earth. The variations of its K.E., P.E. and total energy ( $E$ ) in different orbits is shown in the figure by different curves.
Then for the satellites

Options:

Answer:

Solution:

The K.E. is always positive.

$∴$ The curve C represents the K.E. Both P.E. and total energy are positive but $|E| < |P . E .|$

As P.E. = 2 (Total energy)

$∴$ B represents the total energy and A represents the P.E.
