- 5) Gauss Law is only approximate for finite lines and sheets. In this section you will compare the results of Gauss' Law, calculated for ideal symmetries, with exact calculations using Coulomb's Law. (If the difference between Gauss' Law and exact calculation is less than 2%, it's “good enough for Physics 2 and MasteringPhysics.") a. Circular Disk: The electric field on the axis of a circular disk of charge density o is E,(z) = 1 at a distance of z from the disk. Gauss’ Law predicts a field of E,(z) At what 280 280 +1 V value of z/R does the prediction of Gauss' Law differ from Coulomb's law by 2%? Explain your logic in finding this number. b. Straight Line: In activity 21D we dragged you through the calculation of the electric field a distance r 1 from center of a line of charge of length L. The result was . E = The prediction for an 2trɛ, infinite line is E At what value of r/L does the prediction of Gauss' Law differ from Coulomb’s law by 2%? Explain your logic in finding this…Compare and contrast the properties of the electron and the proton.#11 Electron Volt Measure In #10, recalling that the proton mass is 1.67 x 10-27 kg, what is the velocity of the proton which has passed through a potential difference of 1.00 Volts, acquiring 1.00 electron volts of kinetic energy? It may be useful to recall that K = mv².
- 5. Write down the definition of Gauss's law. Determine how we would obtain Coulomb's law from Gauss's law for a single charged particle. What other types of symmetries are there with Guass's law? Under what circumstance does Gauss's law not behave nicely? give an example.in Millikans oil dropplet experiment How does the direction of the electric charge when the electric field is turned on determine the sign of the charge? Please explain how you can tell
