An unknown configuration of charges creates a uniform electric field. You do not know the electric field's value, but you do know the electric potential values nearby, V(x). Estimate the magnitude of the electric field in the region between x = 8.0 mm. and x = 10.5 mm. VA (x = 4.5mm) is 12.00V, VB (x = 2.0 mm) is 8.00V. Will it point towards A or B? 0.5 0.0 -0.5 -1.0 (mm) A (2.0 mm, 0) B (4.5mm, 0) x (mm)
