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) doesnt exist . But integration is a process in which we add every fraction in the limits of integration which should be an error in the case of integration of charges . So should we use a different method for adding up ( in uniform distribution of charges ) ?
PLZ HELP .... and thanks for spending ur valuable time reading this ...
