Then, you should use the following equation to find the electric field. Read the eBook Section 14.4 2. 5/6 points | Previous Answers MI3 14.4.P.041 You want to create an electric field = < 0, 4 10 4 ,0 > N/C at location < 0, 0, 0>. Where would you place a proton to produce this field at the origin? < 0 0 , -3.72e-6 -1.90e-07 , 0 0 , > m Instead of a proton, where would you place an electron to produce this field at the origin? < 0 0 , 1.9e-7 1.90e-07 , 0 0 , > 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 electric field of a negatively charged object points toward the object. So a proton would be
