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).
