If the escape velocity on the earth is `11.2 km//s`, its value for a planet having double the radius and `8` times the mass of the earth is ...... (in `Km//s`)

`11.2`

`22.4`

`5.6`

`8`

Text Solution

Verified by Experts

The correct Answer is:

`v_(e)=sqrt((2GM)/R)rArr (v_(1))/(v_(2))=sqrt((M_(1))/(M_(2))(R_(2))/(R_(1)))`
