Please help with the following exercise:
Two conductor spheres with radius R and 2R are at a great distance one from the other. We put a charge of Q=+1.7C on the smaller sphere, and then we put them in contact with a conductor thread. Determine what charge the spheres will have at equilibrium. What would not work in our reasoning if the two spheres weren't at a great distance one from the other?
I don't know what relation there is between what we are trying to find and the radius of the sphere. I know that if the spheres had the same radius, the charge at equilibrium between the two would be +Q/2.
I don't know what would not work if the spheres were close, maybe the electric field influencing the motion of charge? I have no clue, please help.
Thank you.
