Keeping mass of a planet constant, its radius is halved. If gravity due to that planet on its surface before this event was g, find the value of gravity after this event (in terms of g).

If the density of a planet is constant, then the curve between value of g on its surface and its radius r will be-

If g is acceleration due to gravity at the surface of the earth, then its value at a depth of 1/4 of the radius of the earth is

A planet has radius ((1)/(36)) th of the radius of the earth. The escape velocity on the surface of the planet was found to be (1)/(sqrt(6)) times the escape velocity from the surface of e earth. The planet is surrounded by a thin layer of atmosphere having thickness h (ltlt radius of the planet). The average density of the atmosphere on the planet is d and cceleration due to gravity on the surface of the earth is g_(e) . Find the value of atmospheric pressure on the surface of the planet.

The mass of a planet is twice the mass of earth and diameter of the planet is thrie the diameter of the earth, then the acceleration due to gravity on the planet's surface is

If g is the acceleration due to gravity on the surface of the earth , its value at a height equal to double the radius of the earth is

The radius of a planet is 1/4 of earth’s radius and its acceleration due to gravity is double that of earth’s acceleration due to gravity. How many times will the escape velocity at the planet’s surface be as compared to its value on earth’s surface
