A 100 V carrier wave is made to vary between 160 V and 40 V by a modulating signal. What is the modulation index ?
Show Hint
- 0.5
- 0.6
- 0.4
- 0.3
The Correct Option is B
Solution and Explanation
\(m=\dfrac{160-40}{160+40}=\dfrac{120}{200}=0.6\).
Answer: (2) 0.6

- 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:
