Please only physics II proficient. I am happy to give a perfect rate unless I get bad work.

Three parallel large uniformly charged planes are arranged as shown in the picture below. Find the electric field at points 1, 2, 3, and 4 if the surface charge densities of the planes are 61 = 45 nC/m, 62 = -70 nC/m, and 63 = -20 nC/m respectively. Assume the positive direction of the vertical axis upwards. 2 3 4 The E-field at point 1, E1 = Units Select an answer v The E-field at point 2, Ez = Units Select an answer v The E-field at point 3, E3 = Units Select an answer v The E-field at point 4, E4 = Unit v Select an answer m/s nc Question Help: Message instructor N/C kg Submit Question V*m N m m/s^2 S no units required
