If v(e) denotes escape velocity and V(...

If `v_(e)` denotes escape velocity and `V_(0)` denotes orbital velocity of a satellite revolving around a planet of radius R, then

A

`v_(e)=sqrt(2)*v_(o)`

B

`v_(e)=2v_(o)`

C

`2v_(e)=v_(o)`

D

`sqrt(2)*v_(e)=v_(o)`

Text Solution

Verified by Experts

The correct Answer is:
A
`v_(e)=sqrt(2Rg)andv_(o)=sqrt(Rg)" " thereforev_(e)=sqrt(2)*v_(o)`
