The value of escape velocity on a certai...

The value of escape velocity on a certain planet is 2 km/s. Then the value of orbital speed for a satellite orbiting close to its surface is:

A

12 km/s

B

1 km/s

C

`sqrt(2)` km/s

D

`2sqrt(2)` km/s

Text Solution

Verified by Experts

The correct Answer is:
C

Near Earth's surface,
`v_(0)=(v_e)/(sqrt2)=(2)/(sqrt2)=sqrt(2)kms^(-1)`
