Wouldn't you use Gauss Law for this?
Inside, zero, no charge is contained.
Pressure=force/area=Eq/area=E*surface charge density.
= Eq/areabubble
A charge of 1nC is added to a spherical soap bubble with a radius of 3.0cm.
What is the electric field strength just outside of the bubble?
What is the electric field strength just inside of the bubble?
The field experienced by each charge in the skin of the bubble is the average of the field strength just inside and the field just outside of the bubble. Given this, what outward pressure (in N/m^2) is exerted on the bubble as a result of it being charged?
