Below are sample questions representative of the exercises included on this worksheet and related 12.106 Electric Charge and Charge Conservation skill assessments:

Problem 1Difficulty: Mastery

A conductor is charged by induction and ends with -6e. If the charging rod and Earth are included in the larger system, what must be true?

ASome other part of the larger system has a total change of +6e.

BThe conductor must have also gained +6e internally.

CCharge conservation requires the conductor to return to zero immediately.

DThe larger system gained -6e from nowhere.

Solution & Explanation:If the conductor gains -6e, the rest of the larger isolated system must change by +6e. Charge is transferred or redistributed, not created.

Problem 2Difficulty: Mastery

Which statement best explains why a neutral object can be attracted to either a positive rod or a negative rod?

AEither rod can polarize the neutral object so the closer side has the opposite sign.

BNeutral objects secretly contain only positive charge.

CPositive and negative rods both create new charge in neutral objects.

DA neutral object must become the same sign as the rod before attraction occurs.

Solution & Explanation:A nearby charged rod can rearrange charge in a neutral object. The side closest to the rod becomes oppositely charged, producing attraction for either rod sign.

Problem 3Difficulty: Mastery

A system starts with total charge -6 microC. After several transfers, two objects in the system have charges -1 microC and +4 microC. What must the combined charge of all remaining objects be?

A-9 microC.

B+3 microC.

C+9 microC.

D-1 microC.

Solution & Explanation:The known two objects total +3 microC. To keep the system total at -6 microC, the remaining objects must total -9 microC.
