Please help with this question please answer both questions A and B Share with your friends Share 0 Vipra Mishra answered this Solution a)Pressure =ForceAreaAs Pressure is inversly proportional to area so as area increases pressuredecreases. In case A area of side which rests on floor is less than area in case BSo From case A to Case B pressure decreases as force that is weight ofbriefcase is constant.b)Pressure =ForceArea =WeightAreaIn case AArea = 20 cm×5 cm =100 cm2= 100×10-4 m2PressureA =60 N 100×10-4 m2 =60×102 N/m2In case BArea = 20 cm×30 cm =600 cm2= 600×10-4 m2PressureB =60 N 600×10-4 m2 =10×102 N/m2 0 View Full Answer
