Two thin conducting plates (very large) parallel to each other carrying total chares `sigma A` and `-2sigma` A respectively (where A is the area of each plates), are placed in a uniform external electric field E as shown. Find the surface charge on each surface.

Two large conducting plates are placed parallel to each other with a separation of 2.00 cm betweeen them. An electron starting from rest near one of the plates reaches the other plate in 2.00 microseconds. Find the surface charge density on the inner surfaces.

Two large conducting plates are placed parallel to each other with a separation of d between them. An electron starting from rest near one of the plates reaches the other plate in time t. If e is the charge on the electron and m is its mass, then the surface charge density on the inner surface is
