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 be

A

`41.4%`

B

`82.8%`

C

`58.6%`

D

`100%`

Text Solution

Verified by Experts

The correct Answer is:
a
`V_(e)=sqrt2V_(c)`
`(V_(e))/(V_(c))=1.414`
`(V_(e)-V_(c))/(V_(c))=1.414-1=0.414=41.4%`.
