Three particles are projected in air with the minimum possible speeds, such that the first goes from Ato B, the second goes from 5 to C and the third goes from C to A. Points A and Care at the same vertical level. The two inclines make the same angle a with the horizontal as shown. Thenthe relation among the projection speeds of the three particles is :
