2. Five charges are arranged as follows • A +2.00 nC charge at the origin.

• A +3.00 nC charge at position, ~rA = 1.00ˆi + 0.50ˆj cm.

• A +3.00 nC charge at position, ~rB = 1.00ˆi − 0.50ˆj cm.

• A -4.00 nC charge at position, ~rC = −1.00ˆi + 0.50ˆj cm.

• A -4.00 nC charge at position, ~rD = −1.00ˆi − 0.50ˆj cm.

Find the total electric force on the 2 nC charge (hint to make this quicker: you can just “brute force” this calculation. But if you use symmetry you can reduce the effort required by at least half.
