I need help with two questions:
1) An object can only have a charge that is an integral multiple of the charge on the ___.
Am I correct with "electron" as the answer? or possibly elementary charge?
2) The difference in potential between any two points in a field is the ___ required to move a unit of whatever is affected by the field between the two points.
Is "work" a possibility? Is "energy" better?
electron.
work; or energy both are correct.
1. yes, electron
2. work is what you mean
in a potential field the work done to move from point A to point B is equal to the change in potential energy
1) You are correct. An object can only have a charge that is an integral multiple of the charge on the electron. The fundamental unit of charge is the elementary charge, which is the charge on a single electron or proton. So, any object can have a charge that is an integer multiple of the elementary charge.
To get this answer, you could have used your knowledge of basic physics or electricity and magnetism. The charge of an electron is a fundamental concept in these fields, and it is commonly understood that charges on objects are quantized in terms of the charge on an electron.
2) For the second question, both "work" and "energy" are possibilities, but "work" is a more appropriate answer. The difference in potential between two points in a field, known as voltage or potential difference, represents the amount of work required to move a unit of charge between those points. Work is the transfer of energy, but in the context of this question, "work" specifically refers to the effort or force exerted to move something against a force or field.
To arrive at this answer, you need to understand the concept of potential in physics and its relationship to work. The potential difference represents the work done per unit charge, so it is associated with the notion of work rather than energy.
