Two concave mirrorsof equal radi of curvature R are fixed on a stand facing opposite directions. The whole system has a mass m nd is kept onn a frictionlesss horiztonal table figure

Two blocks A and B, each of mass m, are placed on the two side of the stnd. At t=0, teh separation between A and the mirrors is 2R and also the separation between B and the mirrors is 2R. The block B moves towards the mirror at a speed v. All collisions which take place are erastic. Taking the original position of the mirrors stand system to be x=0 and X -axis along AB, find the position of the image of A and B at t=
`a. R/(upsilon)`, b. `(3R)/(upsilon)` c. `(5R)/(upsilon)`

Answer

A, B, C, D
