प्रश्न
A pendulum of 100 cm and another pendulum 4 cm long are oscillating at the same time. Calculate the ratio of their time periods.
उत्तर
l1 = 100 cm;
l2 = 4 cm
Let T1 and T2 be the time period of two pendulums.
`"T"_1/"T"_2=sqrt("l"_1/"l"_2)`
`"T"_1/"T"_2=sqrt(100/4)=sqrt(25/1)`
`"T"_1/"T"_2=5/1`
