A cylindrical tube partially filled with water is in resonance with a tuning fork when height of air column is 0.1 m. When the level of water is lowered, the resonance is again observed at 0.35m. The end correction is –

A

0.025 m

B

0.020 m

C

0.015 m

D

0.010 m

Text Solution

Verified by Experts

`v/(4(l_1+e))=n`…(1)
`(3v)/(4(l_2+e))=n`…(2)
From eqn (1) and (2)
e=0.025 m
