Why is the potential energy of two like charges positive and two unlike charges negative?
The potential energy of two like charges is positive because work must be done to bring them together against their natural repulsion. Conversely, the potential energy of two unlike charges is negative because work is released when they come together and move into a lower potential energy state.
What is the formula for calculating the potential energy between two charges?
The formula for calculating the potential energy between two charges is given by U k (q1 q2) / r, where U is the potential energy, k is the Coulomb constant, q1 and q2 are the magnitudes of the charges, and r is the distance between the charges.
What is the potential energy between two point charges?
The potential energy between two point charges is the amount of energy stored in the system due to the interaction of the charges. It is calculated using the formula U k(q1q2)/r, where U is the potential energy, k is the Coulomb constant, q1 and q2 are the magnitudes of the charges, and r is the distance between the charges.
Describe how electric potential energy kinetic energy and work change when two charges of opposite sign are placed near each other?
When two charges of opposite sign are placed near each other, the electric potential energy decreases as they move towards each other due to the attractive force between them. This decrease in potential energy is converted into kinetic energy as the charges accelerate towards each other. Work is done by the electric field in moving the charges and transforming their potential energy into kinetic energy.
What is the formula for calculating the electric potential energy between two point charges?
The formula for calculating the electric potential energy between two point charges is U k (q1 q2) / r, where U is the electric potential energy, k is the Coulomb constant (8.99 x 109 N m2/C2), q1 and q2 are the magnitudes of the charges, and r is the distance between the charges.

Two charges are brought together This results in a corresponding increast in potential energy What can you say about the sign of the two charges Explain?
The charges are the same. To increase the potential energy, the agent must do + work on the charges. If the agent must do + work, then the charges are resisting being brought together.

Which way are charges likely to move between two positions of different electrical potential energy one high and one low?
Charges are likely to move from the position of higher electrical potential energy to the position of lower electrical potential energy. This movement is driven by the principle of minimizing potential energy and achieving equilibrium.
Is voltage potential or kenetic energy?
Voltage is a measure of electric potential energy in a circuit, representing the force that pushes electric charges around a closed loop. It is a potential energy difference between two points in a circuit.
What happens if two charges move to a position of lower potential energy due to an electric field?
When two charges move to a position of lower potential energy due to an electric field, they will experience an attractive force pulling them together. This movement results in a decrease in the distance between the charges, leading to a release of energy in the form of work done by the electric field.
How will two positive charges react?
Two positive charges will repel each other due to the electrostatic force of like charges. This force pushes the charges away from each other, leading to a decrease in their potential energy as they move farther apart.
Will there be a current between the two points if the electrical potential energy at one point in a circuit is greater than the electrical potential energy at another point?
Yes, there will be a current flowing between the two points if there is a difference in electrical potential energy. This potential difference causes charges to move and create an electric current to balance out the potential energy.
What is the difference in potential between two charges called?
Voltage.The correct term for the amount of energy per unit of charge is potential difference.Energy = Charge * VoltageSimple rearranging gives: Voltage = Energy / ChargeTherefore a volt can be defined as a "joule per coulomb".
