Suppose F max=10N for a block . and suppose we apply 8N,there is an equal and opposite force of 8N applied by friction (according to Newtons third law).thus the block will not move .but if 20N is applied ,friction offers 10 N of opposite force and thus the block moves forward with 10N of net force .bUt Newtons third law is violated here when we apply 20N and friction applies 10N..why??
