A nonconducting sphere of radius 10.00 cm carries a uniform volume charge density ρ = 410 nC/m3.

(a) What is the total charge of the sphere?
1.717 nC

Find the electric field at the following radii.

(b) r = 2.10 cm

(c) r = 9.90 cm

(d) r = 10.10 cm

(e) r = 13.6 cm

My attempt at the problem, after manipulating the equation EV=charge inside/[8.85x10^(-12)], was just to insert values into E=Qr/[(4*pi*R^3)*8.85x10^(-12)]; where Q is defined as the total charge, r the radius asked to calculate and R the initial radius.
