$-\mathrm{N}{\mathrm{O}}_2$group has electron withdrawing nature

$-\mathrm{N}{\mathrm{H}}_2$group has electron releasing nature so in para positions$\underset{{\mathrm{\mu }}_1}{\to }$and$\underset{{\mathrm{\mu }}_2}{\to }$will simply add up to give the maximum value of resultant dipole moment of the molecule$\mathrm{ }(\mathrm{\mu }={\mathrm{\mu }}_1+{\mathrm{\mu }}_2)$.
