Two balls are projected simultaneously in same vertical plane from the same point with velocities${\text{V}}_{\text{1}}\text{and}{\text{V}}_{\text{2}}$ with angles ${\theta }_1\text{and}{\theta }_2$  respectively with the horizontal. If ${\text{V}}_{\text{1}}\text{Cos}{\theta }_1={\text{V}}_{\text{2}}\text{Cos}{\theta }_2$ , the path of one ball as seen from the position of another ball is [05 M]
