Physics Waves MHT CET 2024

At the poles of earth, a stretched wire of a given length vibrates in unison with a tuning fork. At the equator of earth, for same setting to produce resonance with same fork, the vibrating length of wire

(A)should be decreasedCorrect
(B)should be increased
(C)should be same
(D)should be three time the original

Answer: (A)

Solution

In the sonometer-type set-up the tension in the wire comes from a weight, . The fundamental frequency is . The acceleration due to gravity is smaller at the equator than at the poles (earth bulges at the equator and the centrifugal
