six planes x, y, z = ±5 if the charge distribution is: (a) twopoint charges, 0.1 μC
at (1,−2, 3) and 17μC at (−1, 2,−2); (b) a uniform line charge of π μC/m at
x = −2, y = 3; (c) a uniform surface charge of 0.1 μC/m2 on the plane y = 3x.

use Gauss' Law

$$\iint \vec E . \hat n \; da = \dfrac{Q_{enc}}{\epsilon_o}$$
