The frequency of a sonometer wire is

100\,\,Hz

. When the weights producing the tension are completely immersed in water, the frequency becomes

80\,\,Hz

and on immersing the weights in a certain liquid, the frequency becomes

60\,\,Hz

. The specific gravity of the liquid is

View answer and explanation

Correct option: B

\begin{array}{llllllllllllllllllll} {1.77} \end{array}

Option B (

\begin{array}{llllllllllllllllllll} {1.77} \end{array}

) is correct because it is the calculated specific gravity of the liquid based on the frequency changes when the weights are immersed in water and the liquid.
