An initially stationary box on a frectionless floor explodes into two places, places A with mass m_(A) and piece B with mass m_(B) . Two pieces then move across the floor along x-axis. Graph of position versus time for the two pieces are given. Baed on the above question, Match column A with the column B. {:(,"Column A",,"Column B (Graph number)",),((P),m_(A) = m_(B),,I,),((Q),m_(A) gt m_(B),,II,),((R ),m_(A) lt m_(B),,III,),(,,,IV,),(,,,V,),(,,,VI,):}
