1. The problem statement, all variables and given/known data In the diagram below, each division on the horizontal axis (the displacement s) is 0.10 m while each division on the vertical axis (the electric potential V) is 1.0 V. What is the electric field component along the displacement axis s in each of the regions specified below? Include the sign of the value in your answer. (a) from 0.0 m to 0.10m (b) from 0.10m to 0.90m (c) from 0.90m to 1.00m 2. Relevant equations ΔV=Vf-Vi = -∫E⋅ds 3. The attempt at a solution I understand that the e-field for a and c is zero. A constant potential means that the e-field isn't changing. My question is about b. The answer is -6.25 V, but I can't wrap my head around what this means. What's the difference between an e-field of +6.25 V and -6.25 V? Is it just the direction the e-field points compared to the direction you're moving?
