The earth moves around the Sun in an elliptical orbit as shown in Fig. The ratio `OA//OB=x`. The ratio of the speed of the earth at `B` to that at `A` is nearly

Answer

`01.00`

Explanation

Applying conservation of angular momentum at position A and B
`mv_(A) xx OA = mv_(B) xx OB`
`rArr v_(B)/v_(A) = (OA)/(OB) = x`
`rArr x^(N) = x`
`rArr N = 1.00`
