(C) The torque $	au$ acting on an electric dipole in an external electric field is given by the formula: $	au = p E \sin 	heta$. Given: Dipole moment $p = 5 	imes 10^{-7} 	ext{ C m}$ Electric field $E = 2 	imes 10^4 	ext{ N C}^{-1}$ Angle $	heta = 60^{\circ}$ Substituting the values: $	au = (5 	imes 10^{-7}) 	imes (2 	imes 10^4) 	imes \sin(60^{\circ})$ $	au = 10 	imes 10^{-3} 	imes \frac{\sqrt{3}}{2}$ $	au = 10 	imes 10^{-3} 	imes 0.866$ $	au = 8.66 	imes 10^{-3} 	ext{ N m}$

An electric dipole with dipole moment $5 \times 10^{-7} \text{ C m}$ is placed in an electric field of $2 \times 10^4 \text{ N C}^{-1}$ at an angle of $60^{\circ}$ with the direction of the electric field. The torque acting on the dipole is:
