a combination of capacitors is set up as shown in figure. The magnitude of the electric field, due to point charge Q( having a charge equal to sum of the charges on the 4uf and 9uf capacitors), at a point distance 30m from it, would equal to


a 4uf capacitor is connected in series with a (3uf and 9uf parallel capacitor) and all this is in parallel to a 2uf capacitors connected to 8v.

option a)240N/C b)360N/C c)420N/C d)480N/C

this question is from jee mains 2016 question 13 physics.
