When a satellite is moving around the earth with velocity `v`, then to make the satellite escape, the minimum percentage increase in its velocity should beA. `41.4%`B. `82.8%`C. `58.6%`D. `100%`

Answer» Correct Answer - a
`V_(e)=sqrt2V_(c)`
`(V_(e))/(V_(c))=1.414`
`(V_(e)-V_(c))/(V_(c))=1.414-1=0.414=41.4%`.
