If an electron is released from rest in a uniform electric field, the electric potential energy of the charge-field system does what?
decreases
If a negatively charged particle is placed at rest in an electric potential field that increases in the positive X direction, what will the particle do?
accelerate in the positive X direction
The figure below is a graph of an electric potential as a function of position. If a positively charged particle is placed at point A, what will its subsequent motion be? (the graph shows that point A is on an upward slope that starts at the y axis and increases until point B, which is in the positive X direction)
The positively charged particle will move to the left, down the ‘slope’ of the graph
The figure below is a graph of an electric potential as a function of position. If a negatively charged particle is placed at point A, what will its subsequent motion be? (the graph shows that point A is on an upward slope that starts at the y axis and increases until point B, which is in the positive X direction)
The negatively charged particle will oscillate around point B (the highest point)
Consider a collection of charges in a given region and suppose all other charges are distant and have a negligible effect. Further, the electric potential is taken to be zero at infinity. If the electric potential at a given point in the region is zero, which of the following statements must be true?
