A block is placed on a rough floor and a horizontal force F is applied on it.The force of friction f by the bloor on the block is measured for different values of F and a graph is plotted between them.

A block is placed on rough floor and a horizontal force F is applied on it. The force of friction f by the floor on the block is measured for different values of F and a graph is plotted between them a) The graph is straight line of slope 450 b) The graph is straight line parallel to the F-axis. c) The graph is straight line of slope 45° for small F and a straight line parallel to the F-axis for large F. d) There is a small kink on the graph

A block of mass 2 kg is placed on the floor (mu=0.4) . A horizontal force of 7 N is applied on the block. The force of friction between the block & floor is f_(s) . Find the f_(s) .
