A block placed on a rough horizontal surface is pulled by a horizontal force F Let f be the force applied by the rough surface on the block . Plot a graph of f versus F .

A block is placed on a 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 block is placed on a rough horizontal plane. A time dependent horizontal force F = Kt acts on the block. Here K is a positive constant. Acceleration time graph of the block is :

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 unknown mass is at rest on a rough, horizontal surface. A horizontal force F is applied to the block. The graph in the figure shows the acceleration of the block with respect to the applied force. The mass of the block is
