The escape velocity for mass is `5.02km//s.f its radius is 3390 km,What is the value of g on its surface

Given mass of the moon is 1/81 of the mass of the earth and corresponding radius is 1/4 of the earth. If escape velocity on the earth surface is 11.2 km / s , the value of same on the surface of the moon is

The escape velocity of a body from the earth's surface is 11.2km//s . The mass of the moon is (1//81)^(th) of that of earth. The radius of the moon is (1//3.7)^(th) that of earth . Find the escape velocity from moon's surface .

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

The escape velocity from the surface of earth is V_(e) . The escape velocity from the surface of a planet whose mass and radius are 3 times those of the earth will be

The escape velocity of a body from the surface of the earth is 11.2 km//s . If a satellite were to orbit close to the earth's surface, what would be its critical velocity?

The value of 'g' at a depth of 80 km will be ( Radius of earth=6400 km and value of 'g' on the surface of earth is 10 m/s^2 )

A body of mass m is on the top point of a smooth hemisphere of radius 5 m. It is released to slide down the surface of the hemisphere. It leaves the surface when its velocity is 5 m//s . At this instant the angle made by the radius, vector of the body with the vertical is

Calculate the value of acceleration due to gravity at a point a. 5.0 km above the earth's surface and b. 5.0 km below the earth's surface. Radius of earth =6400 km and the value of g at the surface of the earth is 9.80 ms^2

The orbital velocity of a body at height h above the surface of Earth is 36% of that near the surface of the Earth of radius R. If the escape velocity at the surface of Earth is 11.2 km s^-1 , then its value at the height h will be

The angular velocity of rotation of star (of mass M and radius R ) at which the matter start to escape from its equator will be
