D3.4. Calculate the total electric flux leaving the cubical surface formed by the six planes ..= ±5 if the charge distribution is: (a) two point charges. 0.1 μC at (1.-2. 3) and μC at (-1.2,-2); (b) a uniform line charge of μC/m at x = -2. = 3: (c) a uniform surface charge of 0.1 μC/m² on the plane = 3x. Ans. 0.243 μC: 31.4 μC; 10.54 μC
