An electron at rest at P 2 (3.3.4) moves along a path ending at Q = {0.1. 1} under the inuence of the electric eld {in newtons per coulomb} 400 9:2 + 22 FI.-y,z) = (3:,D,z). 1. Compute the curl and the divergence of F. Explain what each of the results mean about F . 2. Find a potential function f for F. 3. The potential energy in the case of an electric eld is not just. f. Look in the textbook (16.3. subsection \"conservative elds in physics\"} to see what. additional terms are needed. What is the potential energy equal to? 4. \"-"hat is the electron's speed at point Q? Use Conservation of Energy and the value = 1.76 x IDIIC/kg mE where qe and me are the charge and mass on the electron. respectively. (Hint: You don't need to know the values of :16 and me independently. If you solve for the speed in the Conservation of Energy formula, the speed will depend on the quotient if
