Consider the following situation. A positivecharge q is located a distance R from acharged wire bent into a circular arc asdrawn. The arc has radius R, a net positivecharge Q, and an angular extent of 30° (T/6radians) centered on the same axis as q.15°a. Calculate the electric field (vector)the arc of wire produces at q'slocation. Give the vector incomponent form. The vector onlyhas one component. You shouldwrite down in words an argumentusing the problem's symmetry forthis.b. Find the net force (vector) on q by the arc of wire. Give the vector in component form.c. Compare this force to the force produced by a positive point charge Q located a distance R away from q.Which force is greater, (b) or (c), and by what fraction? Show this algebraically.

The rod carries a uniformly distributed negative charge Q -Q A IR What are the components and E, of the electric field at the origin? Follow the standard four steps. (a) Use a diagram to explain how you will cut up the charged rod, and draw the AE contributed by a representative piece. (b) Express algebraically the contribution each piece makes to the and y components of the electric field. Be sure to show your integration variable and its origin on your drawing. (Use the following as necessary: Q, R, cx, 0, A0, and EQ-) ΔΕ, = - TE aR² AB=(2 Lower limit= 0 ✓ e aR² Upper limit= a X cos(0)40 x (c) Write the summation as an integral, and simplify the integral as much as possible. State explicitly the range of your integration variable. sin (0)40 x Evaluate the integral. (Use the following as necessary: Q, R, a, and E.) Edit
The figure shows a uniformly charged rod withlength a, carrying a total charge of Q. You needto derive an expression for the electric field gen-erated by the rod at point P, which is a distanced below the left end of the rod. (a) Redraw the figure and show clearly how you planto parametrise the rod. Indicate a general in-finitesimal segment and include any vectors rele-vant to your calculation. This figure is an inte-gral part of your calculation, and should providethe reader with enough information to be able tofollow your work. (b) Write down an expression for dE~ , the electric fieldgenerated at point P by an infinitesimal segment.Ensure that the dependence on the parametrisa-tion coordinate is explicit in your expression. (C) Write down an expression for dEx, the x-component of dE~ , and calculate Ex, the x-component of the field at point P. (d) Repeat the steps above to determine the y-component of the field at point P.
As shown in Figure, a particle of charge +Q produces an electric field of magnitude Epart at point P, atdistance R from the particle. As in figure b, that same amount of charge is spread uniformly along a circulararc that has radius R and subtends an angle ?.

Two horizontal plates of opposite charge create a constant electric field E, = 1000 N c directed vertically downwards (scc Figure). An clectron of mass m, and charge -e is fired horizontally with velocity = 0.1c between the plates. Calculate the clectron's acceleration; if the plates have length lo = 1 m, find the clectron's deflection from the horizontal when it cmerges. Neglect gravity in this calculation: is this justified?
