C.1 Three locations, 1, 2, and 3, are labeled in the
electric field diagram. At which of these
locations is the strength of the field the
greatest?i. 1
ii. 2
iii. 3
iv. All three same strengthC.2 Suppose a charged particle is placed in the
field whose diagram is shown here. (a) If a
positively charged particle is placed at point 1,
in what direction will it accelerate? (b) If a
negatively charged particle is placed at point
3, in what direction will it accelerate? (c) At
which of the three locations labeled in the
diagram should a charged particle be placed
so that it experiences the greatest
acceleration?
(a) i. In the direction of the field
ii. Opposite the direction of the field
(b) i. In the direction of the field
ii. Opposite the direction of the field
(c) i. 1
ii. 2
iii. 3
C.3 The electric field created by a uniformly
charged infinite plane is uniform in strength
and perpendicular to the plane. Charged
planes A and B are identical, except that A
has a positive charge and B has the same
magnitude of negative charge. Plane A is
4.0 cm to the left of plane B, and the two
planes are parallel. (a) What direction is the
combined field to the left of A? (b) Halfway
between A and B? (c) To the right of B?
(a) i. To the right
ii. To the left
iii. The combined field is zero
(b) i. To the right
ii. To the left
iii. The combined field is zero
(c) i. To the right
ii. To the left
iii. The combined field is zero(^430) Copyright 2007 Kinetic Books Co. Chapter 23 Problems
