PHY 102 Test Compilation PHY 102 5 Objective Question

Take CBT

Loop: 25 turns, area 2.0×10⁻³ m², current 1.25 A, plane parallel to B=0.2 T. Torque?

A 4.10×10⁻¹ Nm

B 3.26×10⁻¹ Nm

C 2.47×10⁻¹ Nm

D 1.25×10⁻² Nm

Correct Answer

Option D is the correct answer.

Plane parallel to B means normal ⟂ B → sin90=1. τ = N I A B = 25 × 1.25 × 2×10⁻³ × 0.2 = 25 × 1.25 × 4×10⁻⁴ = 25 × 5×10⁻⁴ = 0.0125 Nm = 1.25×10⁻² Nm.

τ = N I A B sinθ.
