Practice question

Given: A dipole with m = 0.7 A m² in B = 0.6 T at 30° has torque: Formula: tau = m B sinθ. Substitution & Calculation: Given: m = 0.7 A m², B = 0.6 T, θ = 30°, sin 30° = 0.5 . tau = 0.7 × 0.6 × 0.5 = 0.21 N m . Final Result: The computed value matches expected outcome and confirms correct choice as per latest NCERT 2026-27.
