Question:
A combination of capacitors is set up as shown in the figure. The magnitude of the electric field, due to a point charge $\mathrm{Q}$ (having a charge equal to the sum of the charges on the $4 \mu \mathrm{F}$ and $9 \mu \mathrm{F}$ capacitors), at a point $30 \mathrm{~m}$ from it , would equal:
Correct Option: , 4
Solution:
