The picture on the right shows a plate capacitor. You may assume that the two plates are very large compared to the separation between the plates (i.e. you may treat them as 'infinite' planes). The plates are charged to ±Q, each plate has an area of A, and the plates are separated by a distance d. The x-axis in this problem is pointing from the negative to the positive plate, with the origin at the negative plate. The electric field at point 2 has a magnitude of E.

A thin rod is bent into a half circle of radius R and centered on the y-axis so that it lies flat in the xy-plane as indicated in the diagram. This glass rod is rubbed all over with silk so that the rod has a total positive charge Q uniformly distributed over the length of the bent rod. Answer the following questions to determine the net electric field at an observation location A located on the positive z-axis a distance d from the origin. (See pic 1 for the following questions) A.

An electron is projected with an initial speed v0 = 1.70×106 m/s into the uniform field between the parallel plates in (Figure 1). Assume that the field between the plates is uniform and directed vertically downward, and that the field outside the plates is zero. The electron enters the field at a point midway between the plates. If the electron just misses the upper plate as it emerges from the field, find the magnitude of the electric field. Express your answer in newtons per coulomb. Suppose that in the figure the electron is replaced by a proton with the same initial speed v0v0. Would the proton hit one of the plates? What would be the direction of proton's displacement? displacement is upward displacement is downward

Problem 1 Shown on the right is an electroscope. The sphere on the top, the leaves at the bot- tom, and the rod connecting them are made by conducting material. The spherical shell that blocks the influence of external electric fields is also made by conducting material but the contact with the rod is insulated, so that charges will not shuffle between the rod and the spherical shell. The electroscope is first negatively charged by touching the sphere with a negatively charged plastic plate. The leaves spread apart and we remove the plastic plate. We then bring a positively charged glass bar close to the sphere without touching the sphere. What happens to the leaves? Leaves (A) One leaf moves higher, the other lower. (B) Nothing changes to the leaves (C) The leaves spread farther apart. (D) The leaves get closer together. Clearly specify/circle your answer, and give a brief explanation.
