3. Induction - Positive Rod

No charge is transferred

Electrons redistributed

Induction with a Positive Rod

Frame 1 - Neutral Electroscope

#p = #e-

Frame 2 - Rod comes near

Charge on electroscope?

#p = #e-

Electroscope is neutral

Charge of Knob (top)?

 Negative

Charge of Leaves?

Positive

Frame 3 - Rod Removed, Charges Return

Electroscope is neutral

What would happen to the leaves of this electroscope if a positively charged rod were brought near the top of the electroscope?

Electrons would be attracted up from leaves toward + rod. Leaves would become more + and diverge more.

Induction Negative
