but in ncert it is given that potential energy is not defined for a single charge,, it is defined for a system of charges....
plzz. correct me

work done in bringing the charge from infinity to this point...
we use superposition...
assume only charge q2 first so the potential will be kq1q2/a
then only charge q3 ... potential will be kq1q3/a
I hope this solves it for u :)

hmm.. that is true..
but the problem is that u have not asked the potential energy of the system but of the single charge!
I hope this helps?
Potential energy is the energy required to bring a charge from infinity to that point ((it is already taken that there are many more charges in the system.. which cause an electric field))
