SNC1W1 Name:____________________________ Electrostatics Practice Quiz This quiz may be completed and handed into your teacher for feedback. It does not count toward your mark. Treat this like a real quiz. Do not use your notes. Give yourself 30 minutes to complete it. NOTE: In order to save paper, I have not provided enough space to answer all questions. Please use a separate piece of paper. 1. Determine the charge on the following object 2. Give the following sphere a -3 charge. [T/I-1] [T/I-1] 3. Choose ONE of the following to answer. Be sure to circle the question you are answering. [A-5] a. A negatively charged balloon is brought near another negatively charged balloon. What will happen? Explain using the Law of Electric Charges? [max. 2 marks] b. A positively charged glass rod is brought close to a small neutral piece of aluminum foil. Using the Law of Electric charges, explain why the aluminum foil moves toward the glass rod. [max. 3 marks] c. Answer question b. but add a diagram to also illustrate your explanation. [max. 5 marks] 4. Choose ONE of the following to answer. Be sure to circle the question you are answering. [A-4] a. If you rub a glass rod with a piece of silk, which material becomes positively charged? Explain using the Electrostatic Series. [max. 2 marks] b. When you rub a balloon on your hair, the balloon sticks to a wall. Explain how friction and the transfer of charges make this happen. [max. 4 marks] SNC1W1 Name:____________________________ 5. In an experiment, a positively charged rod is brought near a metal sphere and a plastic block. Describe what happens in each case and explain why. [A-4 marks] 6. Choose ONE of the following to answer. [T/I-5] a. Show the redistribution of charge when the two rods touch. Include the electric charges on each rod before and after charging by conduction. [max. 3 marks] b. A negatively charged rod comes into contact with a neutral pith ball. Complete the diagrams to illustrate the transfer of charge between the rod and the pith ball. Label the charge of both the pith ball and the rod after they have touched. Use this to explain what will happen if the rod is brough+ c. t near the pith ball again after they have touched.
