1.	A block of mass 50kg is placed as a horizontal table. A spring balance is attached to it and is pulled by gradually increasing the force. When the body just moves, the reading of the spring balance is 50N. Find the coefficient of friction.
Answer» SOLUTION :`mu_(s)=f_(s)//N=f_(s)//mg=50//50xx9.8=0.102`
