- \(\mathrm{SO_2}\)
- \(\mathrm{NO_2}\)
- \(\mathrm{CO}\)
The Correct Option is B
Solution and Explanation
CO2 (greenhouse), NO2 (photochemical smog) and CO (binds haemoglobin) do not have this specific effect.
Answer: (2) SO2

- 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:
