Below are sample questions representative of the exercises included on this worksheet and related 3.8 Static Electricity as an Example of Non Contact Forces (Extension) skill assessments:

Problem 1Difficulty: Mastery

A group records that after rubbing, the balloon attracts paper for 2 minutes, then the effect fades. They repeat and it fades faster on a humid day.

Which explanation best fits BOTH observations?

APaper becomes heavier after 2 minutes.

BHumidity makes balloons stop being rubber.

CTime makes electric forces get stronger forever.

DStatic charge can leak away over time, and humidity helps it leak away faster.

Solution & Explanation:Charge slowly spreads or escapes. Moist air provides pathways for charge to move away, so the non-contact effect fades faster in humidity.

Problem 2Difficulty: Mastery

A student wants to make sure that paper bits move because of static electricity and not because the balloon is ‘sticky.' She places a thin sheet of plastic wrap over the paper bits and holds a charged balloon above the plastic wrap.

Which observation best supports static electricity?

AThe plastic wrap looks shiny.

BThe balloon squeaks when rubbed.

CThe paper bits under the plastic wrap still shift toward the balloon even though they cannot touch it.

DThe table is hard.

Solution & Explanation:If paper moves without contact (and even through a thin barrier), stickiness is not needed. A non-contact electric force can still act.

Problem 3Difficulty: Mastery

Two charged balloons hang from strings. At first they are far apart. The student slowly brings them closer.

Which observation best shows non-contact repulsion (a push) instead of attraction (a pull)?

AAs they get closer, they both fall straight down faster.

BAs they get closer, the balloons swing away from each other and the gap between them increases.

CAs they get closer, they stick together and cannot separate.

DAs they get closer, one balloon turns into a square.

Solution & Explanation:Moving away from each other without touching shows a pushing force at a distance. Like charges repel, causing non-contact repulsion.
