Question #1: Explain what you observed in term of induced charge. 6. Remove the proof plane from the pail, and again note the electrometer reading. If the handle never touched the pail, the reading must be zero. Question #2: Explain why there is electrometer reading only while the charged object is inside? 7. Push the Zero - button to remove any residual charge. Now insert the object again, but let it touch the ice pail. 8. Remove the proof plane. Question # 3: Explain how the ice pail becomes charged. Note the electrometer reading
