### Question

#### In the experiment of balancing moments, suppose the fulcrum is at the 60 cm mark, and a known mass of 2kg is used on the longer arm. The greatest mass of which can be balanced against 2kg such that the minimum distance of either of the masses from the fulcrum is at least 10cm. (Neglect mass of metre scale.) What will be the value of m?

- 12kg
- 4kg
- 6kg

#### The correct answer is: 12kg
