Homework Equations
The Attempt at a Solution
##\oint E\cdot dA = \dfrac{q_{encl}}{\epsilon_0}##To find q_encl would this be correct;
## q_{encl} = \int \dfrac{-\beta}{r^2}\cdot e^{-r/\alpha}\cdot (4\pi r^2)dr##
then integrating that, and substituting it into the expression for q_{encl}.##E = \dfrac{q_{encl} }{\epsilon_0 \cdot 4\pi r^2}##
