Question

Gravitational acceleration on the surface of a planet is √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 the Earth is taken to be 11 km/s, the escape speed on the surface of the planet in km/s will be:

Answer 1

Answer:

The acceleration due to gravity on the surface of a planet of mass Mp and radius Rp is given by, gp=GMp/R2p.

let the gravitational acceleration on the surface be g
