Answer 1

Explanation:

Let, W be the mass of uniform scale,

When the edge is placed at58cm

mark and20gweight suspended at one end, then uniform scale would be balaced.

Applying here the principle of moments:

The uniform scale weight would be balanced at mid point i.e.50cmof the scale.

A weight of 20g is placed at 58cm mark.

So the clockwise moment due to mass of the scale will be

W(50−

42)=

8W

The anticlockwise moment due to mass 20gwill be

20×

(50−

8)=

840.

For equilibrium, clockwise moment = anticlockwise moment

So,

Wx8= 840

W= 105g

The wight of the uniform meter

=

105g.
