so when sphere 3 touches sphere one, the charge is transfered by 1/2. so the force is then 4.45.

when sphere 3 then touches sphere 2 i thought u added the charges? so 4.45N + 8.9N? which is 13.35N?

i think im missing something...

The principle here is that the electrons in the spheres when in contact will move until they are all at equal potential. Since the spheres are identical, what does that tell you about the distribution of charge between the two touching spheres?mb85 said:

i maybe missing something obvious, but i dont see why it is 3/8.
