The weight of the meter stick will be "W".

According to the question,

  • Distance of W to pivot= 10 cm
  • Distance of F to pivot = 10 cm

Let,

  • The weight of meter rule be "F".

We know,

→ [tex]Moment \ of \ a \ force = Force\times distance[/tex]

                       [tex]F \times 10 = W\times 10[/tex]

                              [tex]F = W[/tex]

Thus the answer above is right.
