Problem
If the tension in a stretched string fixed at both ends is increased by 21%, the fundamental frequency is found to be changed by 15 Hz. Then, the
(1) original frequency is 150 Hz
(2) velocity of propagation of the transverse wave along the string increases by 5%
(3) velocity of propagation of the transverse wave along the string increases by 10%
(4) fundamental wavelength on the string does not change
