1. The problem statement, all variables and given/known data The charge density of a spherically symmetric and uniform distribution of charge is ρ = 2*10^-3 C/m^3. An electron is released one centimeter from the center. Find the magnitude and direction of the force onto the electron. 2. Relevant equations charge density = Q/V = Q/[(4/3)pi*r^3] EA = Q(Vgs/Vs) where E is the electric field, A is the area of sphere, Q is the charge of field, and the ratio is the volume of gaussian surface divided by the volume of entire surface. Elementary charge constant for an electron = -1.602 * 10^-19 C 3. The attempt at a solution EA = Q(Vgs/Vs) = E(4pi*r^2) = ρ(4/3)pi*r^3 so E = (1/3)ρ F = qE F = ((1.6*10^-19)(2*10^-3))/3 This is incorrect though and I'm not sure what the solution is. I'm new to Gauss' law and most likely not understanding these equations so any tips/links would be great.
