The escape velocity from the surface of ...

The escape velocity from the surface of earth is `V_(e)`. The escape velocity from the surface of a planet whose mass and radius are 3 times those of the earth will be

A

`v_(e)`

B

`3v_(e)`

C

`9v_(e)`

D

`27v_(e)`

Text Solution

Verified by Experts

The correct Answer is:
a
`v_(e)=sqrt((2GM)/(R))`
`therefore" "v'_(e)=sqrt((2G(3M))/((3R)))=v_(e)`
