1. The problem statement, all variables and given/known data An electric field is given by E = 2xi-3y2j N/C. Find the change in potential from the position rA = i - 2j m to rB = 2i + i + 3k m. 2. Relevant equations VB - VA = -[itex]\int_A^B[/itex] E[itex]\cdot[/itex]ds 3. The attempt at a solution ΔV= -[itex]\int_1^2[/itex]2x dx - [itex]\int[/itex]-3y^2 dy The second integral is supposed to be from -2 to 1 And when I calculate this I get -10 V when the answer is +6 V I also noticed that if I simply invert the limits on the integral I get +6 V, is it just a coincidence or have I calculated the integral wrong?
