1.	The variation of net downward force F on a body on a rough inclined plane versus sine of angle of inclination is shown by the four graphs The correct one is
Answer» . Solution :When a body of mass m is held on a ROUGH inclined plane of inclination `THETA` the net DOWNWARD force on the body is `F = MG sintheta f` wheref is the constant force of friction As `sin theta` increases `F` increases Choice is correct .
