If v0 be the orbital velocity of a sate...

If `v_0` be the orbital velocity of a satellite in a circular orbit close to the earth's surface and `v_e` is the escape velocity from the earth, then relation between the two is .........

A

`v_e =v_o`

B

`sqrt2v_o =v_e`

C

`v_e =v_o/sqrt2`

D

No relation between `v_e and v_o`

Text Solution

Verified by Experts

The correct Answer is:

B

`implies v_e =sqrt(2gR) and v_o = sqrt(gR)`
`:.sqrt 2 v_o =v_e`
