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.
