Actually i need very less out of the problem, i just need to find out the maximum amount of charge possible on the rod, even a rough estimate and then i will charge it with somewhat lesser charge than the acquired answer, but to find out that rough estimate i am not sure if infinite rod...

because this approximation is for infinite charge rod, and for a finite charge rod, the field might be more on the axis, so when i will charge my rod according to calculations of infinite rod, it may discharge from the axis

If a metal rod of 20 cm is charged with 10 μC, then what should be its cross section area so as to prevent electric discharge (electric breakdown) ?

we know that field of a charged rod (infinite, or finite near center) is ~ E= λ/(2πϵr), and maximum possible electric field is 3 x 10^6 N/C, so putting the values we get relation between λ and r, knowing length of rod, we can calculate maximum charge on one rod with respect to radius of cross...

I am trying to charge a system of two metal rods, of definite length, placed a certain distance apart. But before setting up the rods and hooking them to any battery, i wish to know the magnitude of charge that will be accumulated on the rods and what is the maximum possible charge on the rods...
