part 2 The Electric Field of a Continuous Distribution of Charge 1. The problem statement, all variables and given/known data find the electric potential at point p 2. Relevant equations v=Kq/r....v=Er. 3. The attempt at a solution using this pic above and dQ=(Q/L)(dX) v=(K)(dQ)/(L-(X_i)+d) then sub dq=dX(Q/L) we get... (KQ/(L))(dX/(L+d-(X_i)) then integrating V=(KQ/L)((-ln(d))+(ln(L+d))) is this correct? if not could some one tell me where i went wrong. thanks in advance.
