(answers should be in N*m^2/C units)
Constants The three small spheres shown in the figure (Figure 1)carry charges q1- 3.95 nC , g2 =-7.75 nC , and G-250 nC FigureExplanation / Answer
Net flux through the closed surface S1 is phi_1 = q1/eo = (3.95*10^-9)/(8.85*10^-12) = 446.32 Nm^2/C
Net flux through the closed surface S2 is phi_2 = q2/eo = (-7.75*10^-9)/(8.85*10^-12) = -875.71 Nm^2/C
Net flux through the closed surface S3 is phi_3 = (q1+q2)/eo = (3.95-7.75)*10^-9/(8.85*10^-12)
Net flux through the closed surface S4 is phi_4 = (q1+q3)/eo = (3.95+2.5)*10^-9/(8.85*10^-12) = 728.8 Nm^2/C
Net flux through the closed surface S5 is phi_5 = (q1+q2+q3)/eo = (3.95+2.5-7.75)*10^-9/(8.85*10^-12) = -146.89 Nm^2/C
