A graduated uniform metre rod is balanced horizontally on a knife edge at a distance of 10 cm from its centre of gravity, when masses of 50 g and 30 g are suspended at the 5 cm and 90 cm divisions of the rod. Find the weight of the rod.
m1 =50g,m2 =30g,d1 =35cm,d2 =50cmw=?
m1 =50g,m2 =30g,d1 =35cm,d2 =50cmw=?
