Q. In Melde’s experiment, three loops are formed by putting a weight of 8 g in a massless pan. The weight required to form two loop is
A) 18 g
B) 8 g
C) 36 g
D) 24 g
Explanation
(a) Here $p_{1} = 3,\ T_{1} = 8,\ p_{2} = 2,\ T_{2} = ?$
As $\frac{T_{2}}{T_{1}} = \frac{p_{1}^{2}}{p_{2}^{2}}$
$\therefore\ \ T_{2} = \frac{p_{1}^{2}}{p_{2}^{2}} \times T_{1} = \frac{9}{4} \times 8 = 18\ $g
