Solve the following problem given below:
Problem: A solid sphere of radius 40.0 cm has a total positive charge of 20.4 µC uniformly distributed throughout its volume.
Part A: Calculate the magnitude of the electric field at the following distances.
A: 0 cm from the center of the sphere
________________________kN/C
B: 10.0 cm from the center of the sphere
________________________kN/C
C: 40.0 cm from the center of the sphere
________________________kN/C
D: 70.0 cm from the center of the sphere
________________________kN/C
Please use great detail in explaining the solution. Thanks.
