Help with my homework please!
Show all work. Thanks!
An electron is initially moving to the right when it enters a uniform electric field directed upwards, as shown in the figure. Which trajectory (X, Y, Z, or W) will the electron follow in the field? trajectory W trajectory X trajectory Y trajectory Z As a proton moves in the direction the electric field lines it is moving from low potential to high potential and gaining electric potential energy. it is moving from low potential to high potential and losing electric potential energy. it is moving from high potential to low potential and gaining electric potential energy. it is moving from high potential to low potential and losing electric potential energy. both its electric potential and electric potential energy remain constant. The electron-volt is a unit of charge. electric potential. electric force. energy. electric field. A region of space contains a uniform electric field, directed toward the right, as shown in the figure. Which statement about this situation is correct? The potentials at points A and B are equal, and the potential at point C is higher than the potential at point A. The potential at point A is the highest, the potential at point B is the second highest, and the potential at point C is the lowest. The potential at points A and B are equal, and the potential at point C is lower than the potential at point A. The potential at all three locations is the same.Explanation / Answer
4. According to Lorentz force law for electrostatic, we know that direction of force is oppsite to the direction of electric field lines due to the negative charge of the electron. And it drags the electron opposite to the direction of field. So the correct answer is option D) trajectory Z.
5. Potential energy, W = QV(r). For proton, it moves towards the field direction. again potential increases with increasing distance thus increases the potential energy of the proton. so the option C) is right.
6. Definitely it is D) energy.
7. Electric potential is the electric field multiplied by the distance. So increasing distance potential increases. Thus option A) is correct.
