Solution

The correct option is C $50 g f$
Let the weight of the scale be W gf.
According to principle of moments,
Clockwise moment = anticlockwise moment
$(W g f \times 20 c m) = (40 g f \times 25 c m)$
$\Rightarrow W = 50 g f$ .
Thus, the weight of the scale is $50 g f$ .

A uniform meter scale is in equilibrium as shown in figure. Find the weight of the scale.

The correct option is C 50 gfLet the weight of the scale be W gf. According to principle of moments, Clockwise moment = anticlockwise moment (W gf×20 cm)=(40 gf×25 cm) ⇒W=50 gf. Thus, the weight of the scale is 50 gf.
