  • Lightweight conductive sphere A hangs by a string and is free to swing like a pendulum. Identical conductive sphere B is fixed by an insulating rod. Both are initially electrically neutral. An amount Q of positive charge is then transferred from B to A (leaving B with an amount Q of negative charge). When A is brought close to B,

  • A swings toward B (as shown).

  • A swings away from B (not shown).

  • A hangs straight down (not shown, no interaction).

  • Lightweight conductive sphere A hangs by a string and is free to swing like a pendulum. Identical conductive sphere B is fixed by an insulating rod. Both are initially electrically neutral. An amount Q of positive charge is placed upon A. B is grounded. When A is brought close to B,

  • A swings toward B (as shown).

  • A swings away from B (not shown).

  • A hangs straight down (not shown, no interaction).
