1. A positive point charge Q is fixed on As it moves farther and farther from Q, it's
speed will
a very large horizontal keep increasing.
frictionless tabletop. A
second positive point charge
q is released from rest near
the stationary charge and is free
to move. Describe the motion
of q af-ter it is released.
decreases
2. Suppose you have two
negative point charges. As
you move them farther and
farther apart, the poten-tial
energy of this system relative to
infinity work is required to move the negative charge from
point A to point B.
3. A negative charge is moved
from point A to point B along
an equipo-tential surface.
Which of the follow-ing
statements must be true for
this case?
4. Two large, flat, horizontally
oriented E plates are parallel to
each other, a distance d apart.
Half way between the two
plates the electric field has
magnitude E. If the separation
of
the plates is reduced to d/2 what
is the magnitude of the
