You are working on a research project in which you must control the direction of travel of electrons using deflection plates. You have devised the apparatus shown in the figure below. (i) The plates are of length ℓ = 0.750 m and are separated by a distance d = 4.95 cm. Electrons are fired at vi = 5.50×106 m/s into a uniform electric field from the left edge of the lower, positive plate, aimed directly at the right edge of the upper, negative plate. Therefore, if there is no electric field between the plates, the electrons will follow the broken line in the figure. With an electric field existing between the plates, the electrons will follow a curved path, bending downward. (a) Determine the range of angles (in degrees) over which the electron can leave the apparatus. (Assume θ is measured counterclockwise from the +x-axis. Enter your answers as a comma-separated list from smallest to largest. Do not enter units in your answer. ) (θmin, θmax) = ( )。 (b) Determine the electric field (in N/C ) required to give the maximum possible deviation angle. (Enter the magnitude.) N/C

As a torque activity, your Physics TA sets up the arrangement shown below. A uniform rod of mass mr = 173 g and length L = 100.0 cm is attached to the wall with a pin as shown. Cords are attached to the rod at the r1 = 10.0 cm and r2 = 90.0 cm mark, passed over pulleys, and masses of m1 = 266 g and m2 = 167 g are attached. Your TA asks you to determine the following. (a) The position r3 on the rod where you would suspend a mass m3 = 200 g in order to balance the rod and keep it horizontal if released from a horizontal position. In addition, for this case, what force (magnitude and direction) does the pin exert on the rod? Use standard angle notation to determine the direction of the force the pin exerts on the rod. Express the direction of the force the pin exerts on the rod as the angle θF, measured with respect to the positive x-axis (counterclockwise is positive and clockwise is negative). r3 = m Fp = N θF = (b) Let's now remove the mass m3 and determine the new mass m4 you would need to suspend from the rod at the position r4 = 20.0 cm in order to balance the rod and keep it horizontal if released from a horizontal position. In addition, for this case, what force (magnitude and direction) does the pin exert on the rod? Express the direction of the force the pin exerts on the rod as the angle θF, measured with respect to the positive x-axis (counterclockwise is positive and clockwise is negative). m4 = kg Fp = N θF = (c) Let's now remove the mass m4 and determine the mass m5 you would suspend from the rod in order to have a situation such that the pin does not exert a force on the rod and the location r5 from which you would suspend this mass in order to balance the rod and keep it horizontal if released from a horizontal position. m5 = kg r5 = m
