Question
I have some questions that are multiple choice that i cannot figure out! The choices are in the brackets. Thanks for your help!
1. If you were to watch a positive charge as it moves in a region with an electric field, when it moves in the opposite direction as the electric field, its Electric Potential Energy will (remain the same, increase, decrease) as it moves to a region of (simular, higher, lower) potential, while its Kinetic Energy will (remain the same, increase, decrease).
2. If you were to watch a negative charge as it moves in a region with an electric field, when it moves in the opposite direction as the electric field, its Electric Potential Energy will (remain the same, increase, decrease) as it moves to a region of (simular, higher, lower) potential, while its Kinetic Energy will (remain the same, increase, decrease).
3. If you were to watch a positive charge as it moves in a region with an electric field, when it moves in the same direction as the electric field, its Electric Potential Energy will (remain the same, increase, decrease) as it moves to a region of (simular, higher, lower) potential, while its Kinetic Energy will (remain the same, increase, decrease).
4. If you were to watch a negative charge as it moves in a region with an electric field, when it moves in the same direction as the electric field, its Electric Potential Energy will (remain the same, increase, decrease) as it moves to a region of (simular, higher, lower) potential, while its Kinetic Energy will (remain the same, increase, decrease).
5. If you were to watch a positive charge as it moves in a region with an electric field, when it moves in the direction perpendicular as the electric field, its Electric Potential Energy will (remain the same, increase, decrease) as it moves to a region of (simular, higher, lower) potential, while its Kinetic Energy will (remain the same, increase, decrease).
6. If you were to watch a negative charge as it moves in a region with an electric field, when it moves in the direction perpendicular as the electric field, its Electric Potential Energy will (remain the same, increase, decrease) as it moves to a region of (simular, higher, lower) potential, while its Kinetic Energy will (remain the same, increase, decrease).
Explanation / Answer
When a positive charge moves towards the direction of the electric field, its potential energy decreases thereby increasing its kinetic energy.
When a negative charge moves towards the direction of the electric field, its potential energy increases thereby decreasing its kinetic energy.
Movement perpendicular to the electric field has no impact on the PE and KE.
Keeping these in mind, we have:
1) increase, higher, lower
2) decrease, higher, increase
3) decrease, lower, increase
4) increase, lower, decrease
5) remain same, simular, remain same
6) remain same, simular, remain same
