# A 30 kg weight is positioned 2 m from a fulcrum. At what distance from the fulcrum must a 40 kg weight be positioned to keep the scale balanced?

$1.5 \setminus m$

#### Explanation:

Let $x$ be the distance of $40$ kg from the fulcrum then balancing the torque about the fulcrum

$40 g \setminus \times x = 30 g \setminus \times 2$

$x = \frac{60}{40}$

$x = 1.5 \setminus m$
