Gravitational acceleration on the surfac...

Gravitational acceleration on the surfaceof a planet is `(sqrt(6))/(11)` g, where g is the gravitational acceleration on the surface of the earth. The average mass density of the planet is 2/3 times that of the earth. IF the escape speed on the surface of hte earth is taken to be 11 `kms^(-1)`, the escape speed on the surface of the planet in `kms^(-1)` will be.
