Two charges +q and –q, each of magnitude 6.0 × 10–6 C, form a dipole. The separation between the charges is 4 × 10–10 m. Calculate the dipole moment. If this dipole is placed in a uniform electric field E = 3.0 × 102NC–1at an angle 30° with the field, calculate the value of torque on the dipole. |

Answer» 12×10−3NmExplanation:Given data,Charges(Q)=2×10−6C,Distance(d)=3cm=3×10−2m electric field(E)=2×105N/C.TORQUE(τ)=?We KNOW that Torque(τ) to be measuredTorque=charge×distance×Electric fieldTorque(τ)=(2×10−6)×(3×10−2)×(2×105)=12×10−3Nm |
