Q: What is the correct answer for CUET UG Physics Q50?

The correct answer is b. Let's match each item from List-I with its corresponding item in List-II: (A) ∮ B ⋅ ds = 0: If this refers to ∮ B ⋅ dA = 0 (Gauss's Law for magnetism, where dA is an area element), it implies that the net magnetic flux through any closed surface is zero. This fundamental law signifies that magnetic monopoles do not exist, meaning isolated magnetic north or south poles cannot be found. So, (A) matc

Let's match each item from List-I with its corresponding item in List-II:
(A) ∮ B ⋅ ds = 0: If this refers to ∮ B ⋅ dA = 0 (Gauss's Law for magnetism, where dA is an area element), it implies that the net magnetic flux through any closed surface is zero. This fundamental law signifies that magnetic monopoles do not exist, meaning isolated magnetic north or south poles cannot be found. So, (A) matches (IV) monopoles in magnetism do not exist.
(B) Directional property of freely suspended magnet: A freely suspended bar magnet always aligns itself in a particular geographic direction (north-south). This behavior is due to the interaction of the magnet's magnetic dipole moment with Earth's magnetic field, which exerts a torque on the magnet until it aligns. So, (B) matches (III) torque on magnetic dipole.
(C) Never intersect each other: This is a fundamental property of magnetic field lines. Magnetic field lines represent the direction of the magnetic field, and if they intersected, it would imply two different directions for the magnetic field at the same point, which is physically impossible. So, (C) matches (I) magnetic field lines.
(D) Magnetic field of earth: The Earth's magnetic field is believed to be generated by the convection currents of molten iron and other conductive materials in the outer core, effectively creating circulating electrical currents. So, (D) matches (II) circulating ions.
Combining these, the correct option is (A)-(IV), (B)-(III), (C)-(I), (D)-(II).
