Label the diagram of charging by induction.
1: Charged object, 2: Neutral object, 3: Polarization of charge, 4: Ground connection, 5: Induced charge
What is the effect of bringing a positively charged object near a neutral conductor?
The electrons in the conductor will be attracted to the positive charge, causing polarization (separation of charge).
What happens when two objects with like charges are brought close together?
They repel each other with a force described by Coulomb's Law.
What is the effect of grounding an object during induction?
It allows charge to flow either into or out of the object, resulting in a permanent charge opposite to that of the inducing object.
What is the effect of increasing the distance between two charged objects?
The electrostatic force between them decreases (inversely proportional to the square of the distance).
What is the effect of increasing the magnitude of either charge in Coulomb's Law?
The electrostatic force between them increases (directly proportional to the product of the charges).
What is the effect of bringing a positively charged object near a neutral conductor?
Polarization of charge within the conductor, with negative charges attracted to the positive object and positive charges repelled.
What is the effect of grounding a charged conductor?
If negatively charged, electrons flow from the conductor to the ground. If positively charged, electrons flow from the ground to the conductor, neutralizing the charge.
What is the effect of increasing the distance between two charges?
The electrostatic force between them decreases according to the inverse square law.
What is the effect of increasing the magnitude of either charge in Coulomb's Law?
The electrostatic force between the charges increases proportionally.
