Two small charged objects are located as shown in the diagram. In the diagram each square represents 1e-2 m. Q 1 = -4 nC and Q 2 = 7 nC. Remember that 1 nC (nanocoulomb) is 1e-9 coulombs. You wil calculate the net electric field at location = < -0.07 , -0.07 , 0 > m. Before doing any calculations, on a copy of the diagram, draw two arrows representing the
