(a) Show that electrostatic field is conservative. (b) An isolated soap bubble of radius 1 cm is at a potential of 10 V (assume the bubble material is a conductor); calculate the total charge on the bubble. If it collapses to a drop of radius 1 mm (no charge loss or gain during the process), what is the change of the electrostatic energy of the system?![]() |
