Particle A is released from a point on a smooth inclined plane inclined at the angle alpa, with the horizontal. At the same instant another particle B is projected with initial velocity u making an angle beta with the horizontal. Both the particles meet again on the inclined plane. Find the relation between alpha and beta.

1.	Particle A is released from a point on a smooth inclined plane inclined at the angle alpa, with the horizontal. At the same instant another particle B is projected with initial velocity u making an angle beta with the horizontal. Both the particles meet again on the inclined plane. Find the relation between alpha and beta.
Answer» ANSWER :`alpha+beta=(PI)/2`
