A constant electric field is in
the positive X direction as shown in the diagram below. Also shown
are two paths through which a charge can move from point A to point
C. In the first path, the charge moves directly from A to C. In the
second path path the charge moves parallel to the Y-axis to B and
then parallel to the X-axis to C.
Select greater than, less than or equal to for the following
statements.
greater than less than equal to The electric potential
energy of a -14.0 μC charge at point C is ___________ the electric
potential energy of a -14.0 μC charge at point B.
greater than less than equal to The work done on a -14.0
μC charge moved along the first path is __________ the work done on
a -14.0 μC charge moved along the second path.
greater than less than equal to The electric potential
at point A is ___________ the electric potential at point B.
