A proton is released from rest in a region ofspace with a nonzero electric field. (a) As the proton moves, doesthe electric potential energy of the system increase, decrease, orstay the same? (b) Choose the best explanation:I. As the proton begins to move, its kinetic energy increases. Theincrease in kinetic energy is equal to the decrease in the electric potential energy of the system.II. Because the proton has a positive charge, its electric potentialenergy will always increase.III. The proton will move perpendicular to the electric field, andhence its electric potential energy will remain the same

Determine the initial electric potential energy of the system consisting of all four charges with q4 at infinity.

1) A proton is released from rest at x = -2.0 cm in a constant electric field with magnitude 1.50 x10³ N/C, pointing in the positive x-direction. a) Calculate the change in the electric potential energy associated with the proton when it reaches x = 5.0 cm. b) Find the speed of the proton at x = 0.050 m. c) An electron is now fired in the same direction from the same position. What is the change in the electric potential energy associated with the electron if it reaches x = 12.0 cm? d) If the direction of the electric field is reversed and an electron is released from rest at x = 3.0 cm, by how much has the electric potential energy changed when the electron reaches x = 7.0 cm? e) Find the change in electric potential energy as it goes on from x = -0.120 m to x = -0.180 m

As a proton moves in the direction of an external electric fieldA) it is moving from low potential to high potential and the electrical energy of a system consisting of the proton and the electric field is increasing.
