1.

If v_0be the orbital velocity of a satellite in a circular orbit close to the earth's surface and v_eis the escape velocity from the earth, then relation between the two is .........

Answer»

`v_e =v_o`
`sqrt2v_o =v_e`
`v_e =v_o/sqrt2`
No RELATION between `v_e and v_o`

SOLUTION :`IMPLIES v_e =sqrt(2gR) and v_o = sqrt(GR)`
`:.sqrt 2 v_o =v_e`
