The figure shows the variation of energy with the orbit radius of a body in circular planetary motion. Find the correct statements about the curves `A,B` and `C`

A

A shows the kinetic energy, B shows the total energy and C the potential energy of the satellite

B

A and b are kinetic energy and potential energy respectively and C the total energy of the satellite.

C

A and B are the potentital energy and kinetic energy respectively and C the total energy of the satellite .

D

C and A are the kinetic and potential energies and B the total energy of the satellite .

Text Solution

Verified by Experts

The correct Answer is:
B
(b) Kinetic energy of the satellite , `K=(GM_(m))/(2r)`
Potential energy of the satellite, `U= -(GMm)/( r)`
In figure,
Variation of K with r is shown by curve A.
Variation of U with r is shown by curve B.
Variation of E with r is shown by curve C.
