Concentric conducting spheres are located at r = 5 mm and r = 20 mm. The region
Question:
Concentric conducting spheres are located at r = 5 mm and r = 20 mm. The region between the spheres is filled with a perfect dielectric. If the inner sphere is at 100 V and the outer sphere is at 0 V
(a) Find the location of the 20 V equipotential surface.
(b) Find Er,max.
(c) Find r if the surface charge density on the inner sphere is 1.0μC/m2.
