QUESTIONS:
Q22-14) In Fig. 22-24, two objects O1 and O2
have charges +1.0
m
C and -2.0
m
C,
respectively, and a third object, O3, is electrically neutral.
(a)
What is the electric flux through the surface A1 that encloses all the three
objects?
(b)
What is the electric flux through the surface A2 that encloses the third object
only?
Q23-6) If V = 0 at a point in space, must
E
= 0? If
E
= 0 at some point, must V = 0
at that point? Explain. Give examples for each.
Q23-18) If the electric field
E
is uniform in a region, what can you infer about the
electric potential V? If V is uniform in a region of space, what can you infer about
E
?
Q24-6) When a battery is connected to a capacitor, why do the two plates aquire
charges of the same magnitude? Will this be true of the two conductors are different
