The end correction of a resonance column is 1 cm. If the shortest length resonating with the tunning fork is 10 cm, the next resonating length should be :
Show Hint
First resonance: \(L_1+e=\frac{\lambda}{4}\); second resonance: \(L_2+e=\frac{3\lambda}{4}\).

- 28 cm
- 32 cm
- 36 cm
- 40 c
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
\(L_1+e=\frac{\lambda}{4}\Rightarrow 11=\frac{\lambda}{4}\Rightarrow\lambda=44\) cm.
\(L_2+e=\frac{3\lambda}{4}=33\) cm, so \(L_2=33-1=32\) cm.
Answer: (2) 32 cm
\(L_2+e=\frac{3\lambda}{4}=33\) cm, so \(L_2=33-1=32\) cm.
Answer: (2) 32 cm

- Two masses $m$ and $\frac{m}{2}$ are connected at the two ends of a massless rigid rod of length $l$. The rod is suspended by a thin wire of torsional constant $k$ at the centre of mass of the rod-mass system(see figure). Because of torsional constant $k$, the restoring torque is $\tau =k\theta$ for angular displacement $\theta$. If the rod is rota ted by $\theta_0$ and released, the tension in it when it passes through its mean position will be:
