The rough surface of a horizontal table offers a definite maximum opposing force to initiate the motion of a block along with the table, which is proportional to the resultant normal force given by the table. Forces F1 and F2 act at the same angle T with the horizontal and both are just initiating the sliding motion of the block along with the table. Force F1 is a pulling force while the force F2 is a pushing force. F2 > F1, because
