An electric dipole consists of two opposite charges each of magnitude 1.0 µC, separated by a distance of 2.0 cm. The dipole is placed in an external electric field of 1.0 × 10 5 N/C. The maximum torque on the dipole is:
Text Solution
Verified by ExpertsThe correct answer is:
C
τ max = pE sin 90º = 10 –6 × 2 × 10 –2 × 1 × 10 5 N – m
= 2 × 10 –3 N-m
