2₁ Two charges, Q₁- 3.70 μC, and Q₂ 6.00 μC are located at points (0,-2.50 cm) and (0,+2.50 cm), as shown in the figure. 2₁ What is the magnitude of the electric field at point P, located at (6.50 cm, 0), due to Q₁ alone? 6.86x106 N/C You are correct. Previous Tries What is the x-component of the total electric field at P Sb Tries 0/20 What is the y-component of the total electric field at P? Tries 0/20 What is the magnitude of the total electric field at P? Tries 0/20 Now let Q₂-Q₁-3.70 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? Tries 0/20 Given the symmetric situation of the previous problem, what is the magnitude of the force on an electron placed at point P? Tries 0/20
