Torque =pEsin© where ©=angle between p and E p=torque/Esin©=9×10^-25×2/10^-4=18×10^-21 Nm

Use the equation for torque, Torque=P.E=PEsin theta, where P is the dipole moment, E is the electric field and theta is the angle between dipole and the field.From this you substitute the values given above to find the dipole moment of the electric dipole. ie,. 9 * 10^-25 = P * 10^4 * sin30° =P * 10^4 * 1/2 = P * 5 * 10^3 .Therefore, P= 9 * 10^-25/5 * 10^3 = 1.8 * 10 ^-28 Cm.I hope this is the answer......If not then I'm sorry.
