If vibrations of a string are to be increased by a factor of two, then tension in the string must be made
Half
Twice
Four times
Eight times
(c) $n \propto \sqrt T $
A uniform metal wire of density $\rho $, cross-sectional area $A$ and length $L$ is stretched with a tension $T$. The speed of transverse wave in the wire is given by
Length of a string tied to two rigid supports is $40 cm$. Maximum length (wavelength in $cm$) of a stationary wave produced on it is … $cm$
A $43\, m$ long rope of mass $5.0\, kg$ joins two rock climbers. One climber strikes the rope and the second one feels the effect $1.4\, s$ later. What is the tension in the rope …. $N$ ?
A tuning fork gives $4$ beats with $50\, cm$ length of a sonometer wire if the length of the wire is shortened by $1\, cm$. the no. of beats still the same. The frequency of the fork is -…………. $\mathrm{Hz}$
A string is fixed at both ends vibrates in a resonant mode with a separation $2.0 \,\,cm$ between the consecutive nodes. For the next higher resonant frequency, this separation is reduced to $1.6\,\, cm$. The length of the string is …. $cm$
