تمرين 30

Assuming that the electric field intensity is E = a x 100 x (V/m), find the total electric charge contained inside
a) a cubical volume 100 (mm) on a side centered symmetrically at the origin,
b) a cylindrical volume around the z -axis having a radius 50 (mm) and a height 100 (mm) centered at the origin.
