Two planets `A` and `B` have the same material density. If the radius of `A` is twice that of `B`, then the ratio of the escape velocity `(v_(A))/(v_(B))` is

Two planets A and B have the same material density. If the radius A is twice the radius of B then what is the ratio of their escape velocity (V_A/V_B) ?

Two planets A and B have their radii in the ratio r. The ratio of acceleration due to gravity on the planets is x. what is the ratio of the escape velocity from the two planets ?

The mass of a planet is six times that of the earth. The radius of the planet is twice that of the earth. If the escape velocity from the earth is v , then the escape velocity from the planet is:

The mass of a planet is six times that of the earth. The radius of the planet is twice that of the earth. It's the escape velocity from the earth is v , then the escape velocity from the planet is:

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

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

What is the radius of a planet of density rho if at its surface escape velocity of a body is v .

Two strings A and B made of same material are stretched by same tension. The radius of string A is double of the radius of B. A transverse wave travels on A with speed v_A and on B with speed v_B . The ratio v_A/v_B is
