Question
A block is placed on a rough horizontal surface and a horizontal force F is applied to it as shown in figure. The force F is increased from zero in small steps. The graph between applied force and frictional force f is plotted by taking equal scales on axes. The graph is
Options
A.a straight line of slope 45o
B.a straight line parallel to F-axis
C.a straight line parallel to f-axis
D.a straight line of slope 45o for small F and a straight line parallel to F-axis for large F.
