1. The irregularly shaped area of charge in the figure has surface charge density n_i. Each dimension (x and y) of the area is reduced by a factor of 3.57. An electron is very far from the area. What is the ratio F_f / F_i of the electric force on the electron after the area is reduced to the force before the area was reduced? 2. n=Q/A, electric field equation 3. So the ration of the charge densities is n_f/n_i = 12.57. Force is E*q, so dividing the force of the final field by that of the first field, I get q_f/q_i. But what is the charge q of each of these shapes? Since the electron is "very far" is there a difference in the forces it sees comparing the two shapes?
