Below are sample questions representative of the exercises included on this worksheet and related 9.82 Electric Fields and Coulomb Force Concepts skill assessments:

Problem 1Difficulty: Mastery

During a simulation, +2q and -3q at distance d are replaced by +2q and +3q at the same distance d. Which statement is correct?

AThe force magnitude becomes larger because both charges are positive.

BThe force magnitude becomes smaller because there is no negative charge.

CThe force magnitude is unchanged, but the force changes from attraction to repulsion.

DThe force disappears because +3q cancels +2q.

Solution & Explanation:The charge amounts and distance stay the same, so the magnitude stays the same. Changing the sign changes the interaction direction from attraction to repulsion.

Problem 2Difficulty: Mastery

Four lab groups compare charged spheres. Which reasoning correctly identifies the strongest electric force?

AChoose the pair with opposite signs only, because attraction is always stronger than repulsion.

BChoose the pair with the largest charge product after accounting for the smallest separation.

CChoose the pair with the most symmetric charge values, regardless of distance.

DChoose the pair with the largest single charge, even if the spheres are far apart.

Solution & Explanation:Electric force magnitude depends on both charge product and distance. Sign decides attraction or repulsion, but strongest magnitude comes from considering charge amount and separation together.

Problem 3Difficulty: Mastery

Use the field map. Field arrows point inward toward a central source, and the line spacing is closest near the center. Which interpretation is best?

AThe source is neutral, and the arrows show no force direction.

BThe source is negative, and the field is strongest far from the center.

CThe source is negative, and the field is strongest near the center.

DThe source is positive, and the field is weakest near the center.

Solution & Explanation:Inward field arrows indicate a negative source charge. Closer field-line spacing near the center shows the field is stronger there.
