WBJEE · Physics · Motion In One Dimension
Two particles are simultaneously projected in the horizontal direction from a point \(P\) at a certain height. The initial velocities of the particles are oppositely directed to each other and have magnitude \(v\) each. The separation between the particles at a time when their position vectors (drawn from the point \(P\) ) are mutually perpendicular, is
- A \(\frac{v^{2}}{2 g}\)
- B \(\frac{v^{2}}{g}\)
- C \(\frac{4 v^{2}}{g}\)
- D \(\frac{2 v^{2}}{g}\)
