A point charge $Q=5\mathrm{.}33uC$ is located at the center of a cube of side $L=0\mathrm{.}259m.$ In addition, six other identical point charges having $q$

$=-1\mathrm{.}17uC$ are positioned symmetrically around $Q,$ as shown in the figure below. Determine the electric flux through one face of the

cube.
