The plastic ball of the electroscope hangs in midair and is uncharged. Charges cannot move along the silk thread that holds the
ball in the air
Jen completes the following steps in her experiment

4. She rubs the third tube with animal fur for 5 minutes.
Jen's teacher tells her that she can use the pith-ball electroscope to see if any of the rubber tubes are surrounded by an electric
field. What should Jen do to test for an electric field surrounding each tube?
O A. bring the magnet close to the plastic ball and note any motion of the ball toward the magnet
OB.
