A satellite revolving around a planet has orbit velocity 10km/s . The additional velocity required for the satellite to escape from the gravitational field of the planet is

A

14.14 km/s

B

11.2 km/s

C

4.14 km/s

D

41.4 km/s

Text Solution

Verified by Experts

The correct Answer is:
C
The relation between two velocities is given by `v_(e)=(sqrt(2)-1)v_(0)=(1.414-1)v_(0)=0.414xx10=4.14km//s`
