Then, you should use the following equation to find the electric field. 2. 6/6 points Question: MI3 14.4.P.041 You want to create an electric field = < 0, 2 10 4 ,0 > N/C at location < 0, 0, 0>. Where would you place a proton to produce this field at the origin? < , -2.683e-7-2.68e-07 , , > m Instead of a proton, where would you place an electron to produce this field at the origin? < , 2.683e-7 2.68e-07 , , > m (Hint: This problem will be much easier if you draw a diagram.) Solution or Explanation Remember that the electric field of a positively charged object points away from the object, and the...
