what will be the time period of a seconds pendulum if length is one third?

Answer 1

Dear Student,


$$\begin{gathered} T=2\mathrm{\pi }\sqrt{\frac{\mathrm{l}}{\mathrm{g}}} \\ \mathrm{timeperiod}\mathrm{is}\mathrm{T}\mathrm{for}\mathrm{length}\mathrm{l} \\ \mathrm{for}\mathrm{length}\mathrm{l}/3\mathrm{time}\mathrm{period}\mathrm{be} \\ \mathrm{T}\text{'}=2\mathrm{\pi }\sqrt{\frac{\mathrm{l}}{3\mathrm{g}}}=\frac{\mathrm{T}}{\sqrt{3}} \\ \mathrm{Regards} \end{gathered}$$
