Homework Statement
2 conducting spheres with radii 2 & 3m are connected with a conducting rod of thickness 0.1m & length 0.5m. 500C charge is put on the 2m radius sphere.
Find the amount of charge on each sphere & on the rod.
Homework Equations
The Attempt at a Solution
By conservation of charges: Q1 + Q2 + Q3 = 500 ... (1); Q1 of rod & Q2 & Q3 of 2m & 3m radii spheres respectively.
As charges are uniformly distributed we have: [tex]\sigma[/tex]1 = [tex]\sigma[/tex]2 = [tex]\sigma[/tex]3
so Q1/A1 = Q2/A2 = Q3/A3 ... (2)
here i got stuck & don;t know how to continue. i know that i need to find 3 equations with 3 unkowns & solve the system, but I am not seeing these equation except for (1) & probably i have to use parts of (2).
could someone help please. thx
