Unformatted text preview: ximate magnitude of the electric field at P?
(You may assume that the dimensions of the conductors in both the horizontal direction
and the direction into the page are much larger that d, and that point P is far from the edge
of the conductors). A)
E) 100 V/m
150 V/m The electric field inside of the central conductor is zero. Because
the central conductor is neutral the charge density on its top and
bottom surfaces will be equal and opposite. This means that the
field created by the central conductor OUTSIDE of the central
conductor will be zero (much like the field above or below a pair
of infinite planes with charge of equal magnitude and opposite
sign). The distance from the bottom plate to the top plate is 8cm. However, the
middle conductor occupies 4cm, so the distance traversed between the plates
with nonzero electric field is 4cm. Version 1 Page 6 9. A charge of 3 μC is placed at the center of a spherical cavity within a neutral conductor
with a radius of 2 meters, as shown in the diagram. What is the electric field at the outer
surface of the...
