Question

The illustration in figure below shows a uniform metre rule weighing 30 N pivoted on a wedge placed under the 40 cm mark and carrying a weight of 70 N hanging from the 10. cm mark. The ruler is balanced horizontally by a weight Whanging from the 100 cm mark. Calculate the value of the weight W.​

Answer 1

Answer:

125 g

from Equilibrium,

clockwise moment=anticlockwise moment

W×15=75×g×25

m×g×15=75×g×25

∴=

15

75×25

=125g
