Questions
The kinetic energies for a planet in an elliptical orbit about the sun, at positions A, B and C are KA,KB and KC , respectively. AC is the major axis and SB is perpendicular to AC at the position of the sun S as shown in the figure. Then
detailed solution
Correct option is B
If r be the radial distance of a planet from the centre of sun , then conserving energy -1/2 mV2 + (-GMsm / r) = T.E.⇒ K = T.E + GMs m / rNow rA < rB < rC.: KA > KB > KCTalk to our academic expert!
