1. Isolated points of electric charge are called electric charges.
To get the answer to this question, you can refer to any physics textbook or online resource that explains the concept of electric charge. This is a fundamental concept in electricity and magnetism, so you will find a clear definition in any reliable source.
4b. Robert A. Millikan was the American physicist who first measured this fundamental unit of charge.
To find the answer to this question, you can search for information about the measurement of the fundamental unit of charge. Robert A. Millikan conducted the famous oil drop experiment in 1909, which allowed him to determine the charge of an electron.
5. This type of electrification occurs when the charging rod touches an electroscope.
To answer this question, you can use your knowledge of different methods of charging objects. The specific type mentioned here is known as conduction. When a charged rod comes into direct contact with an electroscope, the charge is transferred through the contact, leading to electrification of the electroscope.
6. This type of electrification requires that the charging rod NEVER touch a grounded electroscope.
To answer this question, you need to recall the different methods of charging objects. The specific type mentioned here is known as induction. When a charged rod approaches a grounded electroscope without actually touching it, the charges in the electroscope rearrange themselves without direct contact, leading to electrification.
8. An atom or object that is uncharged is neutral.
To answer this question, you can use your understanding of the concept of charge. An uncharged atom or object has an equal number of positive and negative charges, resulting in a net charge of zero and making it neutral.
12. A charged body of either sign will attract a neutral body by inducing a charge of separation; that is, by temporarily polarizing the neutral body.
To answer this question, you can recall the concept of induction and polarization. When a charged body is brought close to a neutral body, the charges in the neutral body get redistributed, resulting in a temporary separation of charges and attracting the neutral body towards the charged body.
15b. The electric field lines between unlike charges are curved in shape.
To answer this question, you would need to understand the concept of electric field lines. Electric field lines represent the direction and strength of the electric field around charged objects. In the case of unlike charges, the electric field lines curve from the positive charge to the negative charge.
16. The difference in voltage, or potential, between any two points in an electric field equals the work required to move a unit charge between those two positions.
To answer this question, you can refer to the concept of electric potential and voltage. The difference in voltage between two points in an electric field represents the energy required to move a unit charge from one point to another.
17. Equipotential surfaces cross field lines at right angles and are calibrated in volts.
To answer this question, you can refer to the concept of equipotential surfaces. These are imaginary surfaces in an electric field where the electric potential is the same at all points on the surface. Equipotential surfaces intersect the electric field lines perpendicularly, and their values are measured and calibrated in volts.
18a. The closer together the surfaces in question 17 are to each other, the stronger the electric field is at that location.
To answer this question, you can refer to the relationship between equipotential surfaces and electric field strength. The electric field is stronger where the equipotential surfaces are closer together because the change in electric potential per unit distance is greater.
19a. A charge's electrical potential energy within an electric field is calculated as the product of the voltage of its position times the magnitude of its charge.
To answer this question, you can recall the formula for electrical potential energy in an electric field. The potential energy of a charge is given by the product of its charge and the voltage (electric potential) at its position.
