A uniform have metre rule,pivoted at 20cm mark balances horizontally when a mass of 50g is suspended from 4cm mark calculate the mass of the metre rule.
A uniform metre rule of mass 90g is pivoted at the 40cm mark. If the rule is in equilibrium with an unknown mass m placed at the 10cm mark and a 72g mass at the 70cm mark,determine m.
