1. The problem statement, all variables and given/known data I need to estimate the energy loss of electrons before they reach a detector, but I am unsure how to do it. I think I am supposed to integrate the stopping power function over the total distance but I can't solve the equation... 2. Relevant equations Stopping power=-dE/dx Energy loss=∫-dE/dx (I think) 3. The attempt at a solution Is the solution - e*x? Any help is appreciated!
