Question

 If mass of a planet is 12 times the mass of Earth and its radius is thrice that of the Earth then, the escape velocity of the planet will be about ​

Answer 1

Answer:

Because the gravitational force didn't supply it

Answer 2

Explanation:

Escape speed is ve=R2GM=12 km/s on Earth's surface.

Now, the mass of Mars is one-ninth and radius is half that of Earth's.

So,

vm′=R/22G×M/9=32×R2GM=32×12=42  km/s
