2. (70 pts) An electric field of strength 20,000 N/C is inside a parallel-plate capacitor of 1.0 mm spacing. An electron is released from rest at the negative plate. Electron's mass $9.11 \times 10^{-31}$ kg and elementary charge $e = 1.60 \times 10^{-19}$ C. (a) Find the change in potential energy when it reaches the positive plate. (b) Find the electron's speed when it reaches the positive plate?

Let $ f $ and $ g $ be functions defined by in each of the following numbers: Find $ f+g ; f-g ; f \cdot g ; \frac{f}{g} ; f \circ g $ and $ g \circ f $. Also, find the domain and range of the resulting functions. 1. $ f(x)=x^{3}+1 ; g(x)=x-2 $ 2. $ f(x)=\sqrt{4-x^{2}} ; g(x)=\frac{1}{x} $ 3. $ f(x)=\frac{x+2}{x-1} ; g(x)=2 x-1 $ 4. $ f(x)=\frac{1}{x^{2}} ; g(x)=\frac{1}{x} $

Problem # 6 A rod is lying on the top of a table. One end of the rod is hinged to the table so that the rod can rotate freely on the tabletop. Two forces, both parallel to the tabletop, act on the rod at the same place. One force is directed perpendicular to the rod and has a magnitude of 38.0 N. The second force has a magnitude of 55.0 N and is directed at an angle $\theta$ with respect to the rod. If the sum of the torques due to the two forces is zero, what must be the angle $\theta$?
