A uniform metre scale is balanced horizontally on a knife edge at a distance of 10 cm from its centre of gravity, when masses of 50 gm and 30 g are suspended from the 5 cm and 90 cm marks of the rod. What is the weight of the rod?

A uniform meter scale balances at the 40 cm mark when weights of 10g and 20g are suspended from the 10cm and 20cm marks. The weight of the metre scale is

A uniform half metre rule balances horizontally on a knife edge at 29 cm mark when a weight of 20 gf is suspended from one end. What is the weight of the half metre rule ?

A uniform half metre rule balances horizontally on a knife edge at 29 cm mark when a weight of 20 gf is suspended from one end. Draw a diagram of the arrangement.

A uniform metre rule between horizontally on a knife edge placed at the 58cm mark when a weight of 20gf is suspended from one end. (i) Draw a diagram of the arrangement. (ii) What is the weight of the rule?

A uniform metre rule rests horizontally on a knife edge at the 60cm mark when a mass of 10g is suspended from one end. Draw a diagram of the arrangement. (a) At which end must this mass be suspended (b) What is the mass of the rule? (c ) THe 10g mass is now shifted to the 90cm mark. In which direction must the knife edge be shifted to make the rule horizontal again?

A metre scale is balanced on a knife edge at its centre. When a coin of mass 15 g is kept at the 12 cm mark, the scale is found to be balanced at 45 cm. What is the mass of the metre scale?
