Max . Torque $$=$$ $$PE$$ $$=$$ q × a × $$E=$$ $$4$$ × $$10$$–$$8$$ × $$2$$ × $$10$$–$$4$$ × $$4$$ × $$108=$$ $$32$$ ×$$10$$–$$4$$ Nmw $$=$$ $$PE$$(cos0$$º $$-$$ $$cos180$$º$$) $$=$$ $$2$$ $$PE$$ $$=$$ $$64$$ × $$10$$–$$4$$ J

Two opposite and equal charges 4 × 10^–8coulomb when placed 2 × 10^–2 cm away, from a dipole. If this dipole is placed in an external electric field 4 × 10⁸ newton/coulomb, the value of maximum torque and the work done in rotating it through 180^o will be
