Easy

Figure 1 shows a uniform wooden ruler balanced horizontally on a pivot at its centre.

Figure 1

Object A has a weight of 4.5 N.

Calculate the moment of the weight of Object A about the pivot in N m. Use the equation:

moment of a force=force×distance \text{moment of a force} = \text{force} \times \text{distance} moment of a force=force×distance
