Four charges of magnitude Q, a distance x from their neighbour, are arranged as shown. The magnitude of the electric field at points A and B is equal and the direction of the electric field at these two points is indicated in the diagram. O A A +Q +Q 0 B A test charge is moved from A to B along the path shown. Is the work done on moving the test charge from A to B positive, negative or zero?
