If length of stretched string is increased by 50% keeping mass per unit length same, then in order to keep its frequency of vibration constant, its tension must be increased by

View answer and explanation

Correct option: D

1.25

Option D (1.25) is correct because the tension must be increased by a factor of 2.25 to keep the frequency constant when the length is increased by 50%.
