Problem 5 In a simulation, a student released an electron from rest at 0.300 m from a large insulating sheet of charge with uniform surface charge density +2.90 pCm-2. A. Determine the work done on the electron in the electric field of the sheet as the electron moves to a point 0.050 m from the sheet. [5] B. Find the speed that the electron moves with when it is 0.050 m from the sheet. [5]
