There are two inclined planes , each inclined to the horizontal at an angle theta. A particle is projected from a point midway between the foot of the two planes so that it grazes one of the planes and strikes the other at right angle. Find the angle of projection of the projectile(alpha). ans: tan^-1[((sqrt2) – 1)cot thetha] – thetha
