Compute each part of given problem:
Problem: A non conducting solid sphere of radius 2.30 cm carries a uniformly distributed positive charge of 8.30 x 10-9 C.
Part A: Calculate the magnitude of the electric field at a point 1.30 cm away from the center of the sphere.
Part B: Calculate the magnitude of the electric field at a point 3.50 cm away from the center of the sphere.
Please use as much detail as required in solution.
