The maximum and minimum distances of a cornet form Sun are `1.4 xx 10^(12) m and 7 xx 10^(10) m`. If velocity nearest to Sun is `6 xx 10^(4) ms^(-1)`, what is velocity if cornet when it is farthest from the Sun ?

Text Solution

Verified by Experts

`I_(1)omega =I_(2)omega(2) , mr_(1)^(2)(v_(1)//r_(1)) = m_(2)^(2) xx v_(2)//r_(2), 6 xx 10^(4) xx 7 xx 10^(10) = v_(2) xx 1.4 xx 10^(12), v_(2) = 3000 ms^(-1)`
