Four electric charges are arranged as shown. Each charge is placed a distance d = 3.0 cm from the origin, and the values of the charges are q1 = 1.5 µC, q2 = 3.0 µC, q3 = 4.5 µC, andq4 = 6.0 µC.(a) Determine the magnitude of the electric field E at the origin.(b) Determine the direction of the electric field E at the origin. Express your answer as an angle θ, measured counterclockwise from the +x direction.Now an electron of mass m = 9.11×10-31 kg and charge q = −1.60 ×10-19 C is placed at the origin and released from rest.(c) Calculate the magnitude the initial acceleration of the electron.(d) Determine the direction of the initial acceleration of the electron.
