A body is projected with the velocity u1 from the point A as shown in figure. At the same time another body is projected vertically upwards with the velocity u2 from the point B. What should be the value of u1u2 for both the bodies to collide.

Question

A body is projected with the velocity $u_{1}$ from the point $A$ as shown in figure. At the same time another body is projected vertically upwards with the velocity $u_{2}$ from the point $B$ . What should be the value of $\frac{u_{1}}{u_{2}}$ for both the bodies to collide.

\frac{2}{\sqrt{4}}

\frac{2}{\sqrt{3}}

\frac{2}{\sqrt{8}}
