can we talk about dq charge?

Ya ... that's ryt E isn't constant ...

may i know how u conclude it to be the wrong answer ?

a) We know that the smallest charge that can exist is 'e' . But in several instances (such as calculating potential energy of sphere of charge ) we consider 'dq' and then integrate it . How can we justify this ? b) We know that 1/2 or 1/3 of e (charge of electron) doesn't exist . But...

Im sorry that's a spherical shell and i have edited my question .
