1.	A blockof mass2 Kgis placedon a smoothinclinedplaneof inclination30 ^(@)with thehorizontalplane. Find(i) accelerationof theblockand (ii )normal reactionsuppliedby theinclinedplaneon theblock .
Answer» Solution : fromthefigure , (I )accelerationof THEBLOCK`= G sin 30^(@)= 9.8xx(1 )/(2) ` `= 4.9m . S ^(-2) ` (ii )normalreaction, N`= Wcos 30 ^(@)= ( 2 XX 9.8) xx ( SQRT(3) )/( 2) ` `= 9.8 xx 1.732~~ 17 N `
