Question
In (Figure 1) , two objects, O1 and O2, have charges+3.5?Cand ?2.5?C, respectively, and a third object, O3, is electrically neutral.
What is the electric flux through the surface A1 that encloses all three objects?
Express your answer to two significant figures and include the appropriate units.
What is the electric flux through the surface A2 that encloses the third object only?
Express your answer to two significant figures and include the appropriate units.
Explanation / Answer
E=Qenclosed/epsilon =3.5-2.5+0/epsilon
=1.11*10^5
E=0 since charge enclosed is 0
