Question
A uniform metre rule of mass 100g is balanced on a fulcrum at mark 40cm by suspending an unknown mass m at the mark 20cm.
To which side the rule will tilt if the mass m is moved to the mark 10cm ?

Solution
The rule will tilt on the side of mass m (anticlockwise), if the mass m is moved to the mark 10cm.
