Increase
Explanation:
q = Charge in the potassium ion = 
e = Charge of electron = 
= Change in potential = 
Change in electric potential is given by

The energy is 
The potential energy will increase.
More mass will in turn create more force in a collision.
The number of marbles in a collision will affect the outcome because they could bounce off each other and what not.
Because there is no wind, rain, snow, sleet, or people to wear them down,
