The radius of the planet A is half the radius of planet B.If the mass of A is `M_a`,what must be the mass of B so that the vlaue of g on B is half that of its value of A?

The radius of plant A is half the radius of planet B . If the mass of A is M_(A) , what must be the mass of B so that the value of g on B is half of its value on A ?

The radius of the planet A is double the radius of planet B. If the mass of A is M_(A) What must be the mass of B so that the value of g on B is double that of its value on A?

The destiny of a gas A is four times that of gas B. if the molar mass of A is M that of B is

What is the relation between the radius of the nucleus and the mass number?

If the radius of the earth contracts to half of its present radius , then the length of the day will be (if the mass of the earth remaining same)

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

If mass of planet is eight times the mass of the earth and its radius is twice the radius of the earth, what will be the escape velocity for that planet?

Planet A has a mass and radius twice that of Planet B. The escape velocity from Planet A is

Solve the following examples/numerical problems : If the mass of a planet is eight times the mass of the earth and its radius is twice the radius of the earth, what will be the ratio of the escape velocity on the earth to the escape velocity on the planet?

Solve the following examples/numerical problems : If the mass of a planet is 8 times that of the earth and its radius is twice the radius of the earth , what will be the escape velocity for that planet?( Escape velocity for the earth=11.2 km/s)
