1. The problem statement, all variables and given/known data The drawing (a right triangle) show a uniform electric field that points in the negative y direction (pointing down); the magnitude of the field is 3540 N/C, with a=6.2cm, b=7.7cm, and c=9.9cm. Determine the following electric potential differences. a)Vb-Va between points A and B b)Vc-Vb c)Va-Vc 2. Relevant equations 3. The attempt at a solution tried using equation Vb-Va=EPEb/Q-EPEa/Q but problem does not include charges.
