同种材料制成甲乙两个正方体放在水平桌面上甲乙对桌面的压强分别为p1p2把甲放乙上面则乙对桌面的压强为

您好!设甲、乙两物体的密度为ρ,甲的底面积为S1 ,高为h1 ,乙底面积为S2 , 高为h2 P=F/S =G/ S2 =mg/ S2 =(m1 + m2 )g/ S2 =(ρv1+ρv2 ) g/ S2 =( v1+ v2 ) ρg/ S2 P1 = F/S =G/ S1 =mg/ S1 =ρv1 g/ S1所以v1 = S1 P1 /ρg同理：v2= S2 P2 /ρg所以：P=( v1+ v2 ) ρg/ S2 = （S1 P1 /ρg + S2 P2 /ρg）ρg/ S2 = （S1 P1+ S2 P2）/ S2希望我的答案您能够满意!谢谢!
