A planet is revolving in an elliptical orbit about the sun. Its closest distance is R. If `K_(1) and K_(2)` are the maximum and minimum kinetic energies of the planet, `K_(1)//K_(2)`=A. `R//r`B. `sqrt(R//r)`C. `R^(2)//r^(2)`D. 1 |

Answer» Correct Answer - c `(k_(1))/(k_(2))=((1)/(2)mv_(1)^(2))/((1)/(2)mv_(2)^(2))=((v_(1))/(v_(2)))^(2)` `(k_(1))/(k_(2))=((R)/(r))^(2)` |
