A Particle slides down a frictionless parabolic (y=x^(2)0 track(AtoBtoC) starting from rest at a point A as shown in fig. Point B is at the vertex of the parabola and point C is at a height less than that of point. A. After C, the particle moves freely in air as projectile. If the particle reaches heightest point at P, then which of the following are not correct.

1.	A Particle slides down a frictionless parabolic (y=x^(2)0 track(AtoBtoC) starting from rest at a point A as shown in fig. Point B is at the vertex of the parabola and point C is at a height less than that of point. A. After C, the particle moves freely in air as projectile. If the particle reaches heightest point at P, then which of the following are not correct.
Answer» K.E. at P=K.E. at B Height at P=Height at A total ENERGY at P=Total energy at A Time to travel from A to B=Time of travel from B to P Answer :A::B::D
