Example Question #31 : Electricity And Magnetism Exam
Consider a spherical shell with radius and charge
. What is the magnitude of the electric field at the center of this spherical shell?
Possible Answers:
Zero
Correct answer:
Zero
Explanation:
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.
