Lab: Electrostatics PHY 221 IV. Summary questions A. Summarize the methods you used in this lab to do the following: to determine whether or not an object is charged to determine the sign of the net charge on a charged object . to determine whether an object is a conductor or an insulator mova of meta B. Consider the following statement by a physics student who is investigating charge: 1 know that aluminum is a conductor and that plastic is an insulator. That means that aluminum objects can become charged but not plastic objects. Would you agree or disagree with this statement? If you disagree, how would you modify it so that it would be correct? Justify your answer on the basis of your ghservations fromm cond ucur s aluminium is but t is itorrect toat plastic oojectc annor become charaa C. If a positively charged object is used to charge a second object (that was originally neutral) by contact, will the second object be positively charged, negatively charged, or could it be either positively or negatively charged? Explain. heoahie If a positively charged object is used instead to charge a second object (that was originally neutral) by induction, will the second object be positively charged, negatively charged, or could it be either positively or negatively charged? Explain.Explanation / Answer
A)
1) Charged body always creates polarization of charges on a neutral body. if the object is charged, it induces opposite charge on the neutral body and attracts the object other wise not.
2) If we take positive charge towards the object, if it attracts, the object has negative charge other wise it has negative charge.
