WebThe potential energy of the charge $\rho\,dV$ is the product of this charge and the potential at the same point. The total energy is therefore the integral over $\phi\rho\,dV$. ... The mutual energies of two charges is the charge of one times the potential at it due to the other. Or, it can be taken as the second charge times the potential at ... Web12 Mar 2024 · Two positive point charges are 5.20 cm apart. If the electric potential energy is 71.0 microJoules, what is the magnitude of the force between the two charges? Homework Equations potential energy = U = qV E=kq1q2/r^2 F=qE The Attempt at a Solution I've tried manipulating the equations and it does not work.
Web13 Oct 2015 · The potential energy is a property of the system not of an individual component. You can say "the pe of the system of two particles" or "the pe of one in the field of the other". In the second case one of them is "represented" by its field. But you cannot "split" it between the two. Oct 9, 2015 #11 gracy 2,486 83 nasu said: WebElectric potential difference, also known as voltage, is the external work needed to bring a charge from one location to another location in an electric field. Electric potential difference is the change of potential energy …
Web13 Apr 2011 · It's important to note that the electric potential is not the same thing as the electric potential ENERGY. For two point charges, the electric potential energy is given by where r is the distance between the two charges. That's the only reason you're getting the wrong answer. Apr 13, 2011. #3. Web22 Dec 2024 · Electric Potential Between Two Charges At this point you may be wondering why there has been so much talk of charges and electric fields, but no mention of voltage. This quantity, V , is simply electric potential energy per unit charge.
