Q.32
The beam and pans of a balance have negligible mass.
An object weighs W, when placed in one pan and W2
when placed in the other pan. The weight W of the
object is:
(A) VW,W2 (B) (WA+W2)
(C) W,2 +W, (D) (W,'+W,'12​

Answer 1

The weight W of the  object is w = √ w1w2

Explanation:

When object weighs W1.

W1l1  = Wl2 ----(1)

When object weighs W2.

W . l1 = W2l2

Solving equation (1) and (2) we get.

(i) / (ii)  w1 / w = w / w2

w = √ w1w2

Thus the weight W of the  object is w = √ w1w2
