The earth revolves around the sun in an elliptical orbit. It has a speed `v_(1)` when it is at the minimum distance `d_(1)` from the sun. When it is at the maximum distance `d_(2)` from the sun, its speed isA. `(v_(1)d_(2))/(d_(1))`B. `(v_(1)d_(1))/(d_(2))`C. `v_(1)^(2)(d_(2))/(d_(1))`D. `v_(1)((d_(1))/(d_(2)))^(2)` |

Answer» Correct Answer - B By the principle of conservation of momentum, `I_(1)omega_(1)=I_(2)omega_(2)` `therefore md_(1)^(2)(V_(1))/(d_(1))=md_(2)^(2)(V_(2))/(d_(2))" " therefore V_(1)d_(1)=V_(2)d_(2)` |
