उत्तर
Distance = 25 cm = `25/100` = 0.25 m
Force = 10 N
Moment of force = ?
Moment of force = Force × Distance
= 10 × 0.25
= 2.5 N m

Fig. 5 shows a uniform meter scale weighing 200 gf. Provided at its centre. Two weights 300 gf and 500 gf are suspended from the ruler as shown in the diagram. Calculate the resultant torque of the ruler and hence calculate the distance from mid-point where a 100 gf should be suspended to balance the meter scale.
