[Solution] $	au = qdE\sin	heta$: $q = \frac{4}{0.02 	imes 2 	imes 10^5 	imes 0.5} = 2 	imes 10^{-3}$ C. Answer (2).

Q. An electric dipole is placed at an angle of 30° with an electric field intensity $2 \times 10^5$ N/C. It experiences a torque equal to 4 Nm. The charge on the dipole, if the dipole length is 2 cm, is
