A 7 ,3,2kg block placed one over other in this order with 2 at the top coefficent of friction b/w 2kg &3kg is 0.2and b/w 7kg and 3kg is 0.3 when 10 n force app. On 2kg block find acceleration of each assume fric b/w ground and 7kg is 0

Since the applied force is 10 N we will first find the acceleration of the whole system So the system will have an acceleration of 5/6. We know that friction actually opposes relative motion so we will have to go into the referece frame of the blocks to understand the motion.Using that we will get the accelerations to be 13/6 ,19/18 ,5/14 for 2 , 3 and 7 kg respectively.
