PHYS 202 HWK-9 Name:_______________________________ 1. A positively charged particle is moving horizontally when it enters the region between the plates of a capacitor, as the drawing illustrates. (a) Draw the trajectory that the particle follows in moving through the capacitor. (b) When the particle is within the capacitor, which of the following four vectors, if any, are parallel to the electric field inside the capacitor: the particle’s displacement, its velocity, its linear momentum, its acceleration? 2. Draw the electric field lines for two identical negative point charges separated by a small distance. 3. A small object, which has a charge q = 7.5μC and mass m = 9.0 × 10–5 kg, is placed in a constant electric field. Starting from rest, the object accelerates to a speed of 2.0 × 103 m/s in a time of 0.96 s. Determine the magnitude of the electric field. (Ans: 2.5 x 104 N/C)
