An electric dipole with moment p = 4×10⁻⁶ C·m experiences a torque of 1.2×10⁻³ N·m in a 300 N/C field. What is the angle between p and E?
Q1. An electric dipole with moment p = 4×10⁻⁶ C·m experiences a torque of 1.2×10⁻³ N·m in a 300 N/C field. What is the angle between p and E?
Answer: 30°
Explanation: τ = pE sinθ. Option B uses cosine instead of sine in calculation.
