What is the effect of rubbing a balloon on hair?
Electrons transfer from hair to the balloon, making the balloon negatively charged and the hair positively charged.
What happens when a charged rod touches a neutral metal sphere?
Charge is transferred, and the sphere acquires the same type of charge as the rod.
What is the effect of bringing a positively charged object near a neutral conductor?
Negative charges in the conductor move toward the charged object, and positive charges move away, resulting in charge separation.
What happens when you ground a negatively charged object?
Excess electrons flow from the object to the Earth, neutralizing the 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, according to Coulomb's Law).
What is the effect of rubbing a balloon on hair?
The balloon becomes negatively charged (gains electrons), and the hair becomes positively charged (loses electrons).
What is the effect of touching a charged object to a neutral object?
Charge transfers from the charged object to the neutral object, resulting in both objects having the same type of charge.
What is the effect of bringing a charged object near a neutral conductor?
Charges within the conductor redistribute, creating a polarized object (induced charge separation).
What is the effect of grounding a charged object?
Excess charge flows to or from the Earth until the object becomes neutral.
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, according to Coulomb's Law).
What is 'charging' in electrostatics?
Charging is the process of redistributing electrons between objects, not creating charge.
Define 'conservation of charge'.
The total charge in an isolated system remains constant; charge is neither created nor destroyed, only transferred.
What is 'grounding'?
Connecting a charged object to the Earth, allowing excess charge to flow away and neutralize the object.
Define 'induced charge separation'.
The shift of charges within a neutral object when a charged object is brought nearby, creating a polarized object without direct contact.
What does it mean for an object to be 'polarized'?
An object is polarized when its charges have been separated, creating regions of positive and negative charge within the object.
