Two particles are projected simultaneously from the same point, with the same speed, in the same vertical plane, and at different angles with the horizontal in a uniform gravitational field acting vertically downwards. A frame of reference is fixed to one particle. The position vector of the other particle , as observed from this frame, is `vecr`. Which of the following statement is correct?A. `vecr` is a cosntant vector.B. `vecr` changes in magnitudes and direction with time.C. The magnitude of `vecr` increases linearly with time, its direciton does not change.D. The direaction of `vecr` changes with time, its magnitudes may or may not change, depending on the angles of projection.
