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 () in different orbits is shown in the figure by different curves.
Then for the satellites
Then for the satellites
Options
- AA represents the K.E., B & C the P.E. and C the total energy
- BA represents the P.E., B the K.E. and C the total energy
- CA represents the P.E., B the total energy and C the K.E.
- DA represents the total energy, B the K.E. and C the P.E.
Correct answer
C. A represents the P.E., B the total energy and C the K.E.
Step-by-step solution
The K.E. is always positive.
The curve C represents the K.E. Both P.E. and total energy are positive but \left|E\right| < \left|P . E .\right|
As P.E. = 2 (Total energy)
B represents the total energy and A represents the P.E.
The curve C represents the K.E. Both P.E. and total energy are positive but \left|E\right| < \left|P . E .\right|
As P.E. = 2 (Total energy)
B represents the total energy and A represents the P.E.
