Why does a soap bubble expand when it is charged?
 
Physics news on Phys.org
I think it is due to thye repulsive forces acting between the charges.

A hint: the soap bubble takes the shape and size of a surface of minimal energy for the system. Without the charge the soap bubble is a certain size. Why then, would adding charge change it?
