Two balls are placed as shown in Fig. on a "weightless" support formed by two smooth inclined planes each of which forms an angle `alpha` with the horizontal. The support can slide without friction along a horizontal plane. The upper ball of mass `m_(1)` i s released. Determine the condition under which the lower ball of mass `m_(2)` tarts "climbing" up the support.
