Two opposite and equal charges \( 4 \times 10^{-8} \) coulomb when placed \( 2 \times 10^{-2} \mathrm{~cm} \) away, form a dipole. If this
\( \mathrm{P} \) dipole is placed in an external electric field \( 4 \times 10^{8} \)

W newton / coulomb, the value of maximum torque and the work done in rotating it through \( 180^{\circ} \) will be
(A) \( 64 \times 10^{-4} \mathrm{Nm} \) and \( 64 \times 10^{-4} \mathrm{~J} \)
(B) \( 32 \times 10^{-4} \mathrm{Nm} \) and \( 32 \times 10^{-4} \mathrm{~J} \)
(C) \( 64 \times 10^{-4} \mathrm{Nm} \) and \( 34 \times 10^{-4} \mathrm{~J} \)
(D) \( 32 \times 10^{-4} \mathrm{Nm} \) and \( 64 \times 10^{-4} \mathrm{~J} \)
