Total E is x components only Substitute dq to make it solvable Limits of integration: only ¼ of a circle
Definition of Flux Substitution of “B” Substituting “dA” for “b dr” Limits: flux from d to d+a Standard integration Evaluation and “ln” properties Substitution of given “I” function
Using symmetry of a sphere, the E-field due to any area dA is constant, so it can be removed from the integral. dA points to the normal of the sphere, so the angle between E and dA is 0 degrees. dA, when integrated, will be the surface area of the sphere
