Example Question #1 : Understanding Charge Distributions On Objects
Consider a spherical shell with radius and charge . What is the magnitude of the electric field at the center of this spherical shell?
According to the shell theorem, the total electric field at the center point of a charged spherical shell is always zero. At this point, any electric field lines will result in symmetry, canceling each other out and creating a net field of zero at that point.
