An isolated conductor initially free from charge is charged by repeated contacts with a plate which after each contact has a charge Q due to some mechanism. If q is the charge on the conductor after the 1st operation, find the maximum charge which can be given to the conductor in this way.

plz explain.......

hey man something about the conductors should be given dimensions ,capacitance etc.

me

let capastance of conduc. be Cc & that of plalte be Cp. now when fisrt operation is don

me

let capacitance of conduc. be Cc & that of plalte be Cp.

now when fisrt operation is done -----
conduc. has q charge & plate is left with Q - q .
as 2 r in contact potential is same , hence we get---

Q - q/q = Cp/Cc ----------------- 1

now when conduc. has aquired max(say qmax) chage & plate is now brought to contact no chage flow. but again potentials r same.
hecne---

Q/qmax = Cp/Cc ------------------ 2

from 1&2

Q - q/q = Q/qmax or

qmax = Qq/Q - q

eeeeeeeeee
