Question

[On this questionnaire, all batteries are ideal (They have no internal resistances), and connecting wires have no resistance. Unlike most real bulbs, the resistances of the bulbs on this test do not change as the current through them changes. Resistors (R) are shown as] If an object is negatively charged, it means: A. protons have been removed from the object B. protons have been added to the object C. electrons have been removed from the object D. electrons have been added to the object E. neutrons have been removed from the objects When a hard rubber rod is given a negative charge by rubbing it with wool: A. positive charges are transferred from rod to wool B. negative charges are transferred from rod to wool C. positive charges are transferred from wool to rod D. negative charges are transferred from wool to rod E. negative charges are created and stored on the rod To make an uncharged 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 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 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

Option d) is correct

When electrons are added to an particle then the particle becomes negatively charged because electrons are basically negatively charged. Hence on adding that negatively charged particle to another particle then these will also behave like negatively charged particles
