Stationary Waves & Vibrating Strings

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

Show answer and solution

Answer: (a)

$g$ is smaller at the equator, so the tension $T = Mg$ and the wave speed $v = \sqrt{T/\mu}$ decrease.
For the same frequency $n = \dfrac{v}{2L}$ , $L$ must decrease along with $v$ .
So the answer is (a) should be decreased.
