1.	A block P of mass 10 kg is lying on a rough horizontal table and another block Q hangsvertically with the help of ideal string as shown in thefigure.

Answer» block P of mass 10kg is lying on a rough horizontal table block Q hangs vertically with the help of IDEAL string coefficient of friction between table and block is 0.4 To Find:Maximum mass of block Q for which the SYSTEM will be stationarySolution:Free body diagram of block P F(net) = 0T = .4(N)force in vertical DIRECTIONN = mg (take g = 10)T = .4(10)(10)= 40 N resolve tension in the INCLINED spring in vertical and horizontal directionT sin45 = MgT = Mass of block Q is 2.82 kg
