The ratio of escape velocity at earth (v_(e)) to the escape velocity at a planet (v_(p)) whose radius and mean density in twice as that of earth is

The ratio of escape velocity at earth (v_(e)) to the escape velocity at a planet (v_(y)) whose radius and density are twice

The ratio of escape velocity at earth (v_(e)) to the escape velocity at a planet (v_(y)) whose radius and density are twice

The ratio of escape velocity at earth (v_(e)) to the escape velocity at a planet (v_(y)) whose radius and density are twice

The ratio of escape velocity at earth (v_(e)) to the escape velocity at a planet (v_(y)) whose radius and density are twice

The escape velocity for the earth is v_(e) . The escape velocity for a planet whose radius is four times and density is nine times that of the earth, is
