Coulomb's Law: Does Charge Depend on Size?

[daewoo]

Homework Statement

Suppose you let identical pith balls come in contact to make q1=q2 would the charges be equal if the pith balls were of different size?

Homework Equations

F=k(q1)(q2)/r^2

The Attempt at a Solution

I would think they wouldn't be, because doesn't the charge require the radii?

 

[Poop-Loops]

Force requires the distance, which the radius plays into, like your equation shows.

Charge is charge, though. It just means the charge density is bigger or smaller.

 

[pam]

Charge is pretty much locked in place on a pith ball (but not on a conductor).
Very little charge would be transferred between two pith balls in contact.
q1 and q2 could take on any value, independent of the radii.
