Verified By Collegedunia
The Correct Option is B
Solution and Explanation
- The given graph shows the magnetization (M) vs magnetic field (H) curves for different materials. Based on their characteristics:
- Paramagnetism (P) is characterized by a linear increase in M with increasing H.
- Diamagnetism (Q) shows a negative slope for M vs H, meaning the material gets weaker in magnetization as the external magnetic field increases.
- Type-I Superconductivity (R) shows a sharp drop in magnetization once the material reaches the superconducting state, which is consistent with the graph.
Thus, the correct answer is (B).

A wheel of mass \( 4M \) and radius \( R \) is made of a thin uniform distribution of mass \( 3M \) at the rim and a point mass \( M \) at the center. The spokes of the wheel are massless. The center of mass of the wheel is connected to a horizontal massless rod of length \( 2R \), with one end fixed at \( O \), as shown in the figure. The wheel rolls without slipping on horizontal ground with angular speed \( \Omega \).
