Q: What is the correct answer for CUET UG Physics Q43?

The correct answer is d. Let's match each unit/quantity from List-I with its equivalent unit/expression in List-II: (A) 1 T (Tesla): Tesla is the SI unit of magnetic field strength (B). From the definition of magnetic flux (ΦB = BA), 1 T = 1 Weber per square meter (Wb/m²). So, (A) matches (III) Wb/m². (B) 1 H (Henry): Henry is the SI unit of inductance (L). From the relationship ΦB = LI, 1 H = 1 Weber per Ampere (Wb/A). S

Let's match each unit/quantity from List-I with its equivalent unit/expression in List-II:
(A) 1 T (Tesla): Tesla is the SI unit of magnetic field strength (B). From the definition of magnetic flux (ΦB = BA), 1 T = 1 Weber per square meter (Wb/m²). So, (A) matches (III) Wb/m².
(B) 1 H (Henry): Henry is the SI unit of inductance (L). From the relationship ΦB = LI, 1 H = 1 Weber per Ampere (Wb/A). So, (B) matches (IV) Wb/A.
(C) J T⁻¹ (Joule per Tesla): This unit corresponds to magnetic moment (μ). Torque on a magnetic dipole is τ = μBsinθ, so μ = τ/B. The unit of torque is N⋅m (Joule), and the unit of B is Tesla. So, J/T is a unit for magnetic moment. Magnetic moment is also defined as current times area (μ = IA), so its unit is A⋅m². Thus, J T⁻¹ is equivalent to A⋅m² (or 1 m²A). So, (C) matches (II) 1 m²A.
(D) 1 Wb (Weber): Weber is the SI unit of magnetic flux (ΦB). From Faraday's law of induction (EMF = -dΦB/dt), EMF has units of Volts (V) and time has units of seconds (s), so 1 Wb = 1 Volt-second (V⋅s). So, (D) matches (I) V s.
Combining these, the correct option is (A)-(III), (B)-(IV), (C)-(II), (D)-(I).
