1.	A uniform rod of mass M and length L is placed freely on a horizontal table. A horizontal force F is applied perpendicular to the rod at one of its ends. The force F is increased gradually from zero and it is observed that when its value becomes F_(0), the rod just begins to rotate about point O (i) Find length AO (ii) Find F_(0)
Answer» ANSWER :(i) (L)/(SQRT(2))` (ii) `F_(0) = MU MG(sqrt(2)-1)`
