Question

A body weights 8 g when placed in one pan and 18 g when placed on the other pan of a false balance. If the beam is horizontal when both the pans are empty, then the true weight of the body is, 15 g, 13 g, 10 g, 12 g

From figure 8 p = w q ⇒ p q = w 8 .... (i) Now, from figure, w p = 18 q ⇒ p q = 18 w ..... (ii) From equations (i) and (ii), we get p q = w 8 = 18 w w = 18 × 8 = 12 g
