Question

# From an inclined plane two particles are projected with same speed at same angle , one up and other down the plane as shown in figure, which of the following statements is/are correct?

- The time of flight of each particle is the same
- The particles will collide the plane with same speed
- Both the particles strike the plane perpendicularly
- The particles will collide in mid air if projected simultaneously and time of flight of each particle is less than of collision

## The correct answer is: The time of flight of each particle is the same

So, . The acceleration of both the particles is downwards. Therefore, relative acceleration between the two I zero or relative motion between the two is uniform. The relative velocity of w.r.t. is towards, therefore collision will take place between the two in mid air.
