1. [-/6.66 Points] DETAILS SERPSE9 25.P.001.MI.FB. Oppositely charged parallel plates are separated by 6.12 mm. A potential difference of 600 V exists between the plates. (a) What is the magnitude of the electric field between the plates? N/C (b) What is the magnitude of the force on an electron between the plates? (c) How much work must be done on the electron to move it to the negative plate if it is initially positioned 2.92 mm from the positive plate? Need Help? Master It 2. [-/6.66 Points] DETAILS SERPSE9 25.P.004.WI. How much work is done (by a battery, generator, or some other source of potential difference) in moving Avogadro's number of electrons from an initial point where the electric potential is 6.10 V to a point where the electric potential is -6.00 V? (The potential in each case is measured relative to a MJ Need Help? Watch It 3. [-/6.66 Points] DETAILS SERPSE9 25.P.007.MI. An electron moving parallel to the x axis has an initial speed of 3.12 x 105 m/s at the origin. Its speed is reduced to 1.44 x 105 m/s at the point x = 2.00 cm. (a) Calculate the electric potential difference between the origin and that point. Volts (b) Which point is at the higher potential? O the point x = 2.00 cm O both have the same potential O the origin Need Help? Master It 4. [-/6.66 Points] DETAILS SERPSE9 25.P.005.WI. A uniform electric field of magnitude 285 V/m is directed in the negative y direction as shown in the figure below. The coordinates of point @ are (-0.850, -0.850) m, and those of point Bare (0.250, 0.200) m. Calculate the electric potential difference VB - VA using the dashed-line path. . B A
