D 2) 4) 6) 7) 8) LISTA 1 A proton moves in a uniform electric field Eok. The proton is released at the origin with initial velocity vo i. What is the position of the proton at time +? A semi-infinite wire lies on the negative z axis, ffom z = O toz = —oo, with constant linear charge density À. (a) Determine E at a point (0,0, z) on the positive z axis. (b) Determine E at a point (x, 0, 0) on the positive x axis. A hollow cylinder of radius R is uniformly charged with surface charge density o. Use Gauss's Law to determine E forr < Randr > R. Two concentric thin spherical shells, with radii a and b > a, have uniformly dis- tributed charges +Q and — Q respectively. What is E(x) in theregiona
