Identify the correct labels of A,B and C in the following graph from the options given below :
Root mean square speed (Vrms); most probable speed (Vmp); Average speed (Vav)
Root mean square speed (Vrms); most probable speed (Vmp); Average speed (Vav)
Show Hint
- A - Vav ; B - Vrms ; C - Vmp
- A - Vrms ; B - Vmp ; C - Vav
- A - Vmp; B- Vav; C - Vrms
- A - Vmp ; B - Vrms ; C - Vav
The Correct Option is C
Solution and Explanation
Step 2: Numerically \(v_{mp}:v_{av}:v_{rms}=1.414:1.596:1.732\), so \(v_{mp}\lt v_{av}\lt v_{rms}\).
Step 3: In the graph, A is at the peak of the curve (most probable speed) and the lines to its right are B then C in increasing speed. Hence A = Vmp, B = Vav, C = Vrms.
Answer: (C) A - Vmp; B - Vav; C - Vrms

Top JEE Main Questions
- 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:
