physicsQuestions Do any equipotential lines cross one another?Do any field lines cross one another? Estimate the electric field strength at a point :(a) half way between the terminals and(b) near one of the terminals by using the relation: where AV is the potential difference between two points (for example, two points on successive equipotential lines) and AL is the distance measured along a field line. Where is the field the strongest? Where is the field the weakest?
