(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

2 conducting spheres with radii 2 & 3m are connected with a conducting rod of thickness 0.1m & lenght 0.5m. 500C charge is put on the 2m radius sphere.

Find the amount of charge on each sphere & on the rod.

2. Relevant equations

3. The attempt at a solution

By conservation of charges: Q_{1}+ Q_{2}+ Q_{3}= 500 ... (1); Q_{1}of rod & Q_{2}& Q_{3}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 Q_{1}/A_{1}= Q_{2}/A_{2}= Q_{3}/A_{3}... (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 im not seeing these equation except for (1) & probably i have to use parts of (2).

could someone help plz. thx
