Hi,

This is not a puzzle, but a problem based on electrostatics, quite a tricky one. Just try it out ...

2 metallic spheres of the same radius, having charges 1e & 2e are connected by a wire. Find the new charges on the spheres after they are connected..

You need not apply any kind of equations on electrostatic...its more of a puzzle try it!😎 Posted in: #Coffee Room

I think this would be better suited in electrical and electronics section.

Anyhow, let me answer the question.

Not using any equations of electrostatics, I might still use some rules, right?

Well, so, the surface charge densities of two spheres connected by a wire is inversely proportional to the ratio of their radii. Since the radius of both the spheres are equal, the charge densities must also be equal. So, after connecting, each sphere will have 1.5e charge in them.

sir, you are violating a very basic principle: Quantization of charge, i,e. Q=ne, dont you think so? ðŸ˜›
