Question details

Hi I am having trouble with the last two questions. Please show work Two charges, Q1= 4.00 μС, and Q2= 5.40 pC are located at points (0,-4.00 cm ) and (0,+4.00 cm), as shown in the figure What is the magnitude of the electric field at point P, located at (5.50 cm, 0), due to Q1 alone? 7.78×106 N/C You are correct. Previous Tries What is the x-component of the total electric field at P? 1.48x107 N/C You are correct. Previous Tries What is the y-component of the total electric field at P? 1.60x106 N/C ou are correct. Previous Tries What is the magnitude of the total electric field at P? 1.49x107 N/C You are correct. Previous Tries Now let Q2-Q1 4.00 μC. Note that the problem now has a symmetry that you should exploit in your solution. what is the magnitude of the total electric field at P? 6296000 N/C Can you say anything about the y-component of the total electric field before you start calculating? Submit Answer Incorrect. Tries 6/20 Previous Tries Given the symmetric situation of the previous problem, what is the magnitude of the force on an electron placed at point P?
