බෝට්ටුව 200kg . පටවපු බර 1200 එතකොට කොහොම කරන්න ද බං.
බුබුළු පිරිච්ච වතුරෙන් බෝටුටුවට එන උඩුකුරු තෙරපුම් වඩා බෝට්ටුව බරයි කියලා පෙන්නුවොත් හරිද?
ඒත් මෙතන උඩුකුරු තෙරපුම ගන්න බෝටුටුවේ පරිමාව දන්නෙ නෑනෙ
උඩ දීල තියෙන්නෙ අවස්ථා දෙකකට විස්තරේ
බෝට්ටුවෙ පරිමාව V ස්කන්ධය m කියල ගනිං. ඊට පස්සෙ බල සමතුලිත වෙන්න සමීකරණ ලියපං
mg = V*10%*dg
(m+1200)g = V*70%*dg

d වතුරෙ ඝණත්වය දන්නව
සමගාමී සමීකරණ දෙකයි නොදන්න පද දෙකයි V and m
ඒ දෙක ඔය සමීකරණ දෙක විසඳල හොයන්න.
