I see my mistake. Thank you a lot. I know this problem can be easily solved using Gauss Law, i just wanted to do it with all 3 methods.

Hey and thank you for the answer. Apparently i can't edit post so i can't update the first one. Yes, $$\vec{a_R}$$ is a unit vector in R-direction, and R is the length of the same vector. The equation you named is simple a formula for calculating the electric field from a charge distribution...

Hello. I have a problem calculating the electric field from spherical charge distribution. The exercise is: 1. Homework Statement Homework Equations To solve the problem for $$ 0\le R < a$$ i tried 2 ways: $$ \vec{E} = \frac{\vec{a_R}}{4\pi\epsilon_0}\int_v\frac{1} {R^2}\rho dv $$ and the...
