The Electric field at midpoint = E = kq1/r^2 + kq2/r^2
E = (9*10^9/0.11^2)(4.5 + 8.4)*10^-6
E = 9.6*10^6 N/C

A distance of 20 cm separates two particles having charges -8.0 μC and +20.0 μC. What are the magnitude and direction of electric field halfway between these two charges?
Two charges, Q1=2.90 μC, and Q2=5.30 μC are located at points (0,-2.00 cm ) and (0,+2.00 cm), as shown in the figure.
Two charges, Q1=2.90 μC, and Q2=5.30 μC are located at points (0,-2.00 cm ) and (0,+2.00 cm), as shown in the figure. What is the magnitude of the electric field at point P, located at (5.00 cm, 0), due to Q1 alone? The electric field at position P due to charge Q1 is not influenced by charge Q2. Therefore, ignore charge Q2 and apply Coulomb's Law. Remember to convert all units to the SI unit system. What is the x-component of the total...
