Question

Match List I with List II

LIST I
A. Torque
B. Magnetic field
C. Magnetic moment
D. Permeability of free space

LIST II I. [MLT⁻²A⁻²] II. [L²A] III. [MT⁻²A⁻¹] IV. [ML²T⁻²]

Choose the correct answer from the options given below :

G1 Physics · Accepted Answer

Torque: [τ] = [r × F] = [ML²T⁻²] So A → IV. Magnetic force: F = qvB Therefore: [B] = [F/(qv)] = [MT⁻²A⁻¹] So B → III. Magnetic moment: M = IA Therefore: [M] = [AL²] So C → II. From: B = μ₀I dℓ sinθ/(4πr²) we get: [μ₀] = [Br²/(Iℓ)] = [MLT⁻²A⁻²] So D → I. Hence: A-IV, B-III, C-II, D-I
