Gravitational acceleration on the surface of planet is

√6

11

g ; where g is the gravitational acceleration on the surface of earth. The average mass density of the planet is 2/3times that of the earth. If escape speed on the surface of the earth is taken to be 11 kms−1 , escape speed on the surface of the planet in kms−1 , will be :
