The ratio of the escape speed from two planets is 3 : 4 and the ratio of their masses is 9 : 16. What is the ratio of their radii ?

The escape velocity corresponding to a planet of mass M and radius R is 50 km s^(-1) . If the planet's mass and radius were 4M and R , respectively, then the corresponding escape velocity would be
