PALETTE + + 14 12 +4 3 Figure Which of the following statements are true? 1 At location 3 inside the wire the electric field points to the right. 2 The electric field is zero at all locations inside the metal wire. 3 At location 3, the electric field points to the left. 4 The magnitude of the electric field inside the wire is the same at all locations. 5 Mobile electrons inside the wire push each other through the wire. 6 The nonzero electric field inside the wire is created by the moving electrons in the wire. 7 The electric field is parallel to the wire at every location within the wire. 8 The nonzero electric field inside the wire is created by excess charges on the surface of the wire and by the mechanical battery. Your answer should be a list of numbers corresponding to the correct statements, with the numbers separated by commas
