A meter scale is supported on a wedge at its centre of gravity. A body of weight ' \(w\) ' is suspended from the 20 cm mark and another weight of 25 gram is suspended from 74 cm mark balances it and the meter scale remains perfectly horizontal. Neglecting the weight of the meter scale, the weight of the body is
- A 33 gram wt.
- B 30 gram wt.
- C 20 gram wt.
- D 15 gram wt.
Answer & Solution
Correct Answer
(C) 20 gram wt.
Step-by-step Solution
Detailed explanation
\(\begin{aligned} & \mathrm{W}_1 \times l_1=\mathrm{W}_2 \times l_2 \\ & \Rightarrow \mathrm{w} \times 30=25 \times 24=20 \text { gram } \mathrm{wt}\end{aligned}\)
