The one that is extensively used as a piezoelectric material is :
Show Hint
- tridymite
- amorphous silica
- quartz
- mica
The Correct Option is C
Solution and Explanation
It is therefore used in crystal oscillators, watches, radios and pressure sensors.
Amorphous silica has no ordered structure, and tridymite and mica are not used for this purpose.
Answer: (3) quartz

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:
