For a certain stretched string, three consecutive resonance frequencies are observed as 105, 175 and 245 Hz respectively. Then, the fundamental frequency is

A

fixed at both ends, 35 Hz

B

fixed at one end, 35 Hz

C

fixed at both ends, 52.5 Hz

D

fixed at one end, 52.5 Hz

Text Solution

Verified by Experts

The correct Answer is:
B
`f_(1):f_(2):f_(3)=3:5:7 implies f_(1)=3f_(0)=105 implies f_(0)=35Hz`.
