A dumbbell is constructed by fixing small balls each of mass m at the ends of a light rod of length 1 The dumbbell stands vertically in the corner formed by a frictionless wall and frictionless floor After the bottom end is slightly pushed to the right the dumbbell begins to slide Denoting acceleration due to gravity by g if any time t the upper ball is leaving the wall then at that instant A Tension in the rod is zero B Acceleration of lower ball is zero 8g C speed of lower ball is m s V27 2
