Q:
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 _____N/C (c) r = 9.90 cm _____kN/C (d) r = 10.10 cm _____N/C (e) r = 13.6 cm _____N/C 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.
