An object is projected with kinetic energy $\displaystyle K$ from a point $\displaystyle A$ at an angle $\displaystyle 60$° with the horizontal. The ratio of the difference in kinetic energies at points $\displaystyle B$ and $\displaystyle C$ to that at point $\displaystyle A$ (see figure), in the absence of air friction is :
