Practice question

Given: A rectangular loop of area 0.06 m² with 15 turns carries 2.5 A in a field of 0.8 T at 60° to the plane. What is the torque? These values define the system as per NCERT data. Formula: tau = N I A B sin θ, where θ = 60° to plane means sin 30° with normal. This is standard NCERT relation. Substitution & Calculation: tau = 15 × 2.5 × 0.06 × 0.8 × sin 60° = 1.8 × 0.866 = 1.5588 approx 1.56 N m . Result: The computed value matches expected outcome and confirms correct choice as per NCERT.
