A proton in an electric field is initially located at Point
P_(1)
on the
x
-axis. The proton is given an initial velocity in the positive
x
-direction, moves in a straight line along the axis, and continually slows down and comes instantaneously to rest at Point
P_(2)
. What can be concluded about the electric potential at points
P_(1)
and
P_(2)
, and what evidence or reasoning supports the claim? 5PCEMA19 The electric potential is greater at Point
P_(1)
. The proton's kinetic energy is greatest at Point
P_(1)
. The electric potential is greater at Point
P_(1)
. The electric field does positive work on the proton as it moves from Point
P_(1)
point to Point
P_(2)
. The electric potential is greater at Point
P_(2)
. The proton experiences a force directed toward Point
P_(2)
while it is in motion. The electric potential is greater at Point
P_(2)
. The proton's kinetic energy decreases as it moves toward Point
P_(2)
.
