An object of mass m is dropped onto the surface of two planets, X and Y, which have no atmosphere. The height from which the object is dropped and the change in gravitational potential energy of the object, for each planet, are given in the table. [Table showing height and change in gravitational potential energy for planet X and planet Y] The acceleration of free fall near the surface of planet X is gx. What is the acceleration of free fall near the surface of planet Y?
A3/4 gx
B4/3 gx
C3gx
D4gx
