Physics Conducting Spheres
posted by andrew .
1. Two concentric conducting spherical shells have radii of 0.145 m. and 0.215 m. The inner sphere bears a charge of -3.00E-08 C. An electron escapes from the inner sphere with negligible speed. Assuming that the region between the spheres is a vacuum, compute the speed (in meters/second) with which the electron strikes the outer sphere.
is this possible as there is no electric field inside of a conductor?
