The radius of a planet is double that of the earth but then average densities are the same. If the escape velocities at the planet and at the earth are `v_(P)` and `v_(E)` respectively, then prove that `v_(P)=2 v_(E).`

The radius of a planet is double than that of the earth but their average densities are the same. If the escape velocities of the planet and the earth are v_p and v_e respectively, then prove that v_p=2v_e .

The radius of a planet is double that of earth but their average are the same. If the escape velocities at the planet and the earth are v_(p) and v_( e) respectively , then prove that v_(p) = 2 v_(e) .

The radius of a planet is twice that of the earth but its average density is the same. If the escape speed at the planet and at the earth are v_(p) and v_(e) , respectively, then prove that v_(p)=2v_(e)

The radius of a planet is 1/4th of Re and its acc. due to gravity is 2g. What would be the value of escape velocity on the planet, if escape velocity on earth i v_(e)

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:

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:

Acceleration due to gravity on a planet is 10times the value on the earth . Escape velocity for the planet and the earth are V_(f) and V_(e) respectively Assuming that the radii of the planet and the same then

Planet A has massa M and radius R. Planet B has half the mass and half the radius of Planet A.If the escape velocities from the Planets A and B are v_(A) and v_(B), respectively , then (v_(A))/(v_(B))=n/4. The vlaue of n is :
