Challenge Problems
Push your limits with challenges.
Question 1
Determine the torque acting on an electric dipole with a dipole moment of 2 × 10^-6 C·m, oriented at an angle of 60° in a field of strength 5 × 10^3 N/C.
💡 Hint: Use the torque formula τ = pE sin(θ).
Question 2
If an electric dipole is rotated from an aligned position to a position perpendicular to the electric field, calculate the change in torque experienced if the dipole moment is kept constant.
💡 Hint: Recall what happens to torque when the angle changes from 0° to 90°.
