Below are sample questions representative of the exercises included on this worksheet and related 9.81 Electric Charge and Static Electricity skill assessments:

Problem 1Difficulty: Mastery

Identical conducting spheres A, B, and C are used in sequence. A starts at +6 units, B is neutral, and C starts at -2 units. A touches B and separates; then B touches C and separates. What is B's final charge?

A+2 units.

B-0.5 units.

C+3 units.

D+0.5 units.

Solution & Explanation:A and B first share +6 units, so each becomes +3 units. Then B shares charge with C: +3 plus -2 gives +1 unit total, which divides equally to +0.5 units on each sphere.

Problem 2Difficulty: Mastery

A student tries to charge a sphere by induction with a negative rod. The student brings the rod near, connects the sphere to ground, removes the rod, and then disconnects the ground. Why does the sphere fail to keep a positive charge?

AThe negative rod must touch the sphere for induction to work.

BPositive charge cannot exist on a metal sphere.

CGrounding always makes every object permanently negative.

DRemoving the rod before disconnecting ground lets electrons flow back and neutralize the sphere.

Solution & Explanation:For induction to leave a net charge, the ground must be removed while the charged rod is still nearby. If the rod is removed first, grounding allows the sphere to return to neutral.

Problem 3Difficulty: Mastery

Two objects A and B are rubbed together and then tested. A attracts neutral paper scraps, B attracts neutral paper scraps, and A attracts B. What is the best interpretation?

AA and B likely have opposite net charges produced by electron transfer.

BA and B must both be neutral because both attract paper.

COnly A is charged because B was charged by magnetism.

DA and B must have the same sign because both attract paper.

Solution & Explanation:Both charged and neutral objects can attract neutral paper, so that test alone is not enough. Attraction between A and B after rubbing is consistent with opposite charges from electron transfer.
