A charge of 87.6 pC is uniformly distributed on the surface of a thin sheet of insulating material that has a total area of 29.2 cm^2. A Gaussian surface encloses a portion of the sheet of charge. If the flux through the Gaussian surface is 5.00 N.m^2/C, what area of the sheet is enclosed by the Gaussian surface?

A Gaussian surface in the form of a hemisphere of radius R = 5.40cm lies in a uniform electric field of magnitude E = 2.50 N/C. Thesurface encloses no net charge. At the (flat) base of the surface,the field is perpendicular to the surface and directed into thesurface.

(a) What is the flux through the base?
_____N·m2/C

(b) What is the flux through the curved portion of thesurface?
_____N·m2/C

Figure shows a spherical Gaussian surface and a charge distribution. When calculating the flux of electric field through the Gaussian surface, the electric field will be due to

The figure shows four gaussian surfaces surrounding the distribution of charges.
