8. (a) State Gauss's law in electrostatics. You are given three different spheres with different surface area S1, S2 and S3, containing the same charge +Q in each case. If S1>S2>S3, which sphere will give the highest net electric flux, justify your answer? (b) There are two parallel charged plates are placed vertically separated by distance of 0.08 m. If the left plate is negatively charged plate (red) with charge density o_ = 0.45 C/m2 and right plate is positively charged plate (black) with charge density o4 = 0.55 C /m² as Figure 7 shown in Fig. 7, calculate the net electric field at middle point P between those plates. Also specify its direction.
