18 Three identical balls A B and C each of mass m connected by three identical springs when placed on a frictionless horizontal floor occupy corners of an equilateral triangle as shown in the figure This assembly is suspended by attaching the ball A to the ceiling with the help of a light thread What can you predict regarding accelerations of the balls immediately after the thread is cut Acceleration of free fall is g a All the balls will have downward acceleration g b All the balls have acceleration greater than g in different directions c Acceleration of the upper ball is 3g downwards and the accelerations of the lower balls are vanishingly small d Acceleration of the upper ball is 3g downwards and the lower balls move apart with finite accelerations 19 In the setup shown the pulleys the cords and the spring are ideal and masses of the loads are indicated in the figure Initially the system is in equilibrium What should be the range of mass M so that acceleration of 000mor greater than acceleration of free fall
