    The radius of a planet is (1)/(4) of earth's radius and it's acceleration due to gravity is double that of the earth's acceleration due to gravity. How many times will the escape velocity at the planet's surface be as compared to it's value on the earth's surface

    A bullet is fired vertically upwards with a velocity upsilon from the surface of a spherical planet when it reaches its maximum height, its acceleration due to the planet's gravity is (1)/(4)th of its value at the surface of the planet. If the escape velocity from the planet is V_("escape") = upsilon sqrt(N) , then the value of N is : (ignore energy loss due to atmosphere).
