    A non-conducting solid sphere with diameter of d = 40 cm carries 100 μC electric charges, which are distributed uniformly throughout its volume. Using Gauss's law

    a) Find the electric field strength 10 cm from the sphere's center E (r = 10 cm)

    b) Find the electric field strength 20 cm from the sphere's center E (r = 20 cm)

    c) Find the electric field strength 30 cm from the sphere's center E (r = 30 cm)
