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 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 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:

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)

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

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

The value of the escape velocity from the earth is v_e . If the radius of a planet is 4 times that of the earth and its density is 9 times the density of the earth, then the value of the escape velocity from that planet will be
