26 Questions
This imbalance in the electric charges is what causes the two materials to exhibit a net electric charge and depending on the nature of the material, it could be an attractive or ______ force
repulsive
Charging by induction is done when an already charged object is brought close to another object which causes the electrons in the latter to ______
interact
Charging by contact is done by placing a charged object in contact with a ______ object
neutral
If a negatively charged object is made to contact with a neutral object, the net repulsive force of the charges causes them to flow towards the neutral object until all charges are evenly distributed between the two objects. This process is known as ______
neutralization
Grounding is the process of returning any charged objects into a ______ state.
neutral
The earth provides a very large buffer space for electric charges to disperse thus no imbalance is created when ______ is performed.
grounding
Charge Conservation is the principle that the total electric charge in an isolated system never changes. The net quantity of electric charge is always ______.
conserved
Coulomb's Law states that the force between two charged objects is directly proportional to the product of their charges and inversely proportional to the square of the distance between their ______.
centers
Grounding helps in eliminating excess ______ from an object
charge
Coulomb's Law describes the electrostatic interaction between ______ charges
electric
Neutralization is the process of combining an acid with a base to form water and a salt, resulting in the removal of excess ______
charge
Charge conservation principle states that electric charge can neither be created nor destroyed, only ______ from one form to another
transferred
What is the equation that represents Coulomb's Law?
F = (kq1q2)/r^2
What does the proportionality constant 'k' represent in Coulomb's Law?
The constant 'k' represents the electrostatic constant or Coulomb's constant.
How does the force between two charged objects change with an increase in distance according to Coulomb's Law?
The force between two charged objects decreases as the square of the distance between them increases.
What is the unit of the proportionality constant 'k' in Coulomb's Law?
The unit of 'k' is Nm^2/C^2.
Who is credited with the discovery and formulation of Coulomb's Law?
Charles-Augustin de Coulomb
Explain the significance of the square of the distance in the Coulomb's Law equation.
The square of the distance in the equation accounts for the spreading out of the force over a larger area, resulting in the diminishing of the force as the distance increases.
What principle does Coulomb's Law describe in terms of the interaction between charged objects?
Electrostatic interaction
What is the force between two charged objects proportional to in Coulomb's Law?
Product of their charges
In Coulomb's Law, what is the relationship between the force and the distance between the charged objects?
Inversely proportional to the square of the distance
What is the principle that the total electric charge in an isolated system never changes known as?
Charge Conservation
What fundamental principle does Coulomb's Law describe in terms of the interaction between two charged objects?
Coulomb's Law describes the electrostatic interaction between charged objects.
Who is credited with developing the concept of Coulomb's Law and the proportionality constant involved?
Charles-Augustin de Coulomb
What does Coulomb's Constant represent in the context of Coulomb's Law?
Coulomb's Constant represents the proportionality constant in Coulomb's Law.
How does the electric force between two charged objects change with respect to the distance between them according to Coulomb's Law?
The electric force between two charged objects is inversely proportional to the square of the distance between them.
Learn about the process of charging by induction in electronics engineering, where an already charged object causes electrons in another object to interact. Discover how this process leads to the exhibition of net electric charges and attractive or repulsive forces between materials.
