An electron at rest at p = (5,3,7) moves along a path ending at q = (1, 1, 1) under the influence of the electric field (in newtons per coulomb)

f(x, y, z) = 400(x^2 + z^2)^-1 (x, 0, z).

a)find a potential function for f

b) what is the electron’s speed at the point q? (use conservation of energy and the value qe/me = −1.76 × 1011 c/kg, where qe and me are the charge and mass on the electron, respectively
