Two artificial satellites of the same mass are moving around the earth in circular orbits of different radii. In comparision to the satellite with lesser orbital radius, the other satellite with higher orbital radius will have:

A

greater kinetic energy

B

less potential energy

C

greater total energy

D

less magnitude of angular momentum, about the centre of the circular orbit.

Text Solution

Verified by Experts

The correct Answer is:
C
`K.E.=(GMm)/(2R), PE=-(GMm)/R`
`T.E.=-(GMm)/(2R)`
Angular momentum `mvR=msqrt(GMR)`
