Question

Two satellites have their masses in the ratio 3:1. The radii of their circular orbits are in the ratio 1:4. What is the total mechanical energy of A and B?

Answer 1

Answer:

HEY MATES.......❇

Mechanical energy is conserved so long as we ignore air resistance, friction, etc... energy is lost to friction in the sense that it is not converted between potential and kinetic energy but rather into heat energy, which we cannot put back into the object.

Answer 2

Answer:

Total energy  T.E.=2r−GMm 

Now Total energy for p, Tp=2rp−GMm

similarly Tq=2rq−GMm

Taking the ratio we get, TqTp=2rp−GMm×−GMm2rq=rprq . Given rqrp=3.

Therefore, TqTp=31
