Question

A planet is revolving in an elliptical orbit around the sun. it's closest distance from sun is r and the farthest distance is R. if k1 & k2 are maximum and minimum kinetic energy of planet then find k1/k2.

Answer 1

here planet moving in elliptical orbit and we know that angular momentum is conserved because net torque is zero .

using above principal we can solve this problem...

see attachment....

hope it will help u.
