Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Chalk is a soft, white, porous sedimentary material made mostly of calcium carbonate (calcite) from the shells of microscopic marine organisms.
Because it is formed by the accumulation and compaction of such sediments, it is classed as a sedimentary rock (a form of limestone), not as a single mineral, wood or polymer.
Answer: (1) Rock

- 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:
