Consider a spherical Gaussian surface and three charges:q1=1.76microC, q2= -2.50microC, and q3=3.69microC. Find the electric flux through the Gaussian surface if it completely encloses
(a) only chargeq1 & q2
(b) only chargesq2 and q3, and
(c) all three charges. Suppose a 4th charge, Q, is added to part C. Find sign and magnitude of Q required to give zero electric flux through the surface.
