A combination of capacitors is set up as shown in the figure. The magnitude of the electric field, due to a point charge $\displaystyle Q$ (having a charge equal to the sum of the charges on the $\displaystyle 4 \mu \mathrm{~F}$ and $\displaystyle 9 \mu \mathrm{~F}$ capacitors), at a point distant $\displaystyle 30$ m from it, would equal :
Official answer
(3)
$\displaystyle 420$ N/C
