53. a recently discovered planet has a mass four times as great as earth's and a radius twice as large as earth's. what will be the approximate size of its gravitational field?

so gravity will be same as that of surface of earth

Explanation:

As we know that the acceleration due to gravity is given as

here we have

we know that for earth we have

now if the radius and mass is given as above

so gravity will be same as that of surface of earth

the gas collects in coils that then becomes a liquid that then flows through the coils inside the refrigerator
