Two charges, - Q and - 3Q, are a distance apart. These two charges are free
Question:
Two charges, - Q and - 3Q, are a distance ℓ apart. These two charges are free to move but do not because there is a third (fixed) charge nearby. What must be the magnitude of the third charge and its placement in order for the first two to be in equilibrium?
