In turntable shown in figure, block A has mass 0.9 kg and mass of 1.7 kg and the blocks are 13 cm from the axis of rotation. The coefficient of static friction between all the surface is 0.1. Consider the friction and mass of pulley negligible. Find angular speed of rotation of turntable for which the blocks begin to slide.
