a sphere of radius R lies on a horizontal surface.A boy wants to throw a ball over the sphere with minimum possible speed so that the ball is just able to cross the cylinder. Q.1 the minimum speed of projection of ball reqired to cross the sphere is? Q.2 angle of projection for that minimum speed is θ, then cos θ=? Q.3 Distance of point of projection from lowest point of sphere for minimum speed of projection is?
