Question

Ion this questionnaire, all baterries are ideal ahey have no internal resistance). and connecting wires have no resistance, most real bulbs, the resistances of the bulbs on this test do not change as the current through them changes Resistors (R) are shown 1 ir an object is negatively charged, t means A protons have been removed som the object B protons have been added to the object C. eleeters have been emowed tom te object D electrons have been added to the object E. neurons have been removed from the objects 2 when a hardneeer rod is given a negative charge by nabbing it with wool A posieve charges are transferred from rod to wool B, negatve charges are transferred from rod to wool C. positive charges are transferred from wool to rod D. negate charges are transferred from wool to rod E. negative charges are oreated and stored on the rod 3 To make an unchanged object have a negative charge we must: A add some atoms B. remove some atoms C, add some electrons D, remove some electrons E. write down a negative sign 4, An electrical insulator is a material A containing no electrons B. through which electrons do not flow easily C. which has more electrons than protons on its surface D, cannot be a pure chemical element E. must be a crystal 6. An electron traveling north enters a region where the electric field is uniform and points west. The electron: A, speeds up B, slows down C. veers east D, veers west E. continues with the same speed in the same direction

Explanation / Answer

1) D electrons are added to the object

(for netitively charged particle Possesses more electrons than protons)

2D) When a hard rubber rod is given a negative charge by rubbing it with wool, negative charges are transferred from wool to rod.

3) C.add some electrons

4) B.through which electrons do not flow easily

5) C. slow down

Because the charge of the electron is negative, the force on it, F = qE is pointed backwards and the electorn will slow down.
