A 25 m long antenna is mounted on an antenna tower. The height of the antenna tower is 75 m. The wavelength (in meter) of the signal transmitted by this antenna would be :
Show Hint
- 200
- 400
- 100
- 300
The Correct Option is C
Solution and Explanation
Antenna length \(l = 25\) m (the 75 m tower height is only a distractor, as the tower just supports the antenna).
\(\lambda = 4l = 4 \times 25 = 100\ \text{m}\).
Answer: (3) 100

- 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:
