A solid sphere of radius 40.0 cm has a total positive charge of 33.7 µC uniformly distributed throughout its volume. Calculate the magnitude of the electric field at the following distances.

(a) 0 cm from the center of the sphere
(b) 10.0 cm from the center of the sphere
(c) 40.0 cm from the center of the sphere
(d) 60.0 cm from the center of the sphere
