Induction - Charging w/o contact
Conduction and Induction
St. Mary's H.S.
No charge is transferred
Electrons redistributed
Case II - Induction w/ Negative Rod
Frame 1 - Neutral Electroscope
#p = #e-
Frame 2 - Rod comes near
Compare #p with #e-
#p = #e-
Electroscope is neutral
Knob (top) Positive
Leaves - negative
Frame 3
Rod Removed, Charges Return
Electroscope is neutral
Which diagram best represents the charge distribution on three neutral spheres when a positively charged rod is brought near sphere x, but does not touch it?
Jan. 2003 Regents
Choice 4
Electrons are attracted to rod
