SUMMARY
The charge of a soap bubble with a radius of 0.1 mm and a wall thickness of 3.3 x 10-8 m, charged to a potential of 100 V, can be calculated using the formula Q = CV, where C is the capacitance of the bubble. The capacitance for a spherical shell is given by C = 4πε0R, where R is the outer radius. In this case, the outer radius is effectively 0.1 mm since the wall thickness is negligible compared to the radius. Therefore, the charge can be derived as Q = 4πε0(0.1 x 10-3) * 100.
