Question

Please answer Part D of the question.

Item 4 4 of 8 Part C Constants Assume that two of the electrons at the negative terminal have attached themselves to a nearby neutral atom. There is now a negative ion with a charge-2e at this terminal. What are the electric potential and electric potential energy of the negative ion relative to the electron? Learning Goal To understand electrical potential, electrical potential energy, and the relationship between them The electric potential and the electric potential energy are both twice as much. Electric potential and electric potential energy are related but different concepts. Be careful not to confuse the terms. Electrical potential energy UE is the potential energy that a charge q has due to its position relative to other charges. The electric potential V at a specific position is a measure of the amount of potential energy per unit charge a particle of net charge q would have at that position. In other words, if a charge q has an electric potential energy Up, the electric potential V at the location of q is The electric potential is twice as much and the electric potential energy is the same The electric potential is the same and the electric potential energy is twice as much The electric potential and the electric potential energy are both the same The electric potential is the same and the electric potential energy is increased by the mass ratio of the oxygen ion to the electron The electric potential is twice as much and the electric potential energy is increased by the mass ratio of the oxygen ion to the electron UE Recall that the gravitational potential energy (Ug-mgy) of an object of mass m depends on where you define y- 0. The difference AUg in gravitational potential energy between two points is the physically relevant quantity. Similarly, for electric potential energy, the important quantity is the change in electric potential energy: ??? AV. This is why we often just measure the potential difference ??. When we say that the potential of a car battery is 12 V, we mean that the potential difference between the positive and negative terminals of the battery is 12 V. Previous Answers Correct Part D What is the electric potential energy of an electron at the negative end of the cable, relative to the positive end of the cable? In other words, assume that the electric potential of the positive terminal is 0 V and that of the negative terminal is -12 V.

Explanation / Answer

Given that

V = UE/q

UE = q*dV

Given that

q = -1.6*10^-19

dV = -12 - 0 = -12 V

So,

UE = (-1.6*10^-19)*(-12)

UE = 19.2*10^-19 J
