362113 Two towers $AB$ and $CD$ are situated at distance $d$ apart as shown in figure. $AB$ is 20 $m$ high and $CD$ is 30 $m$ high from the ground. A particle is thrown from the top of $AB$ horizontally with a velocity of $10{ms}^{-1}$ towards $CD$. Simultaneously, another particle is thrown from the top of $CD$ at an angle ${60}^{\circ }$ to the horizontal towards $AB$ with the same magnitude of initial velocity as that of the first object. The two particles move in the same vertical plane, collide in mid-air, calculate the distance $d$ between the towers.
