1) Four point charges lie along the x axis in our problem. They are: +1 μC at x = -0.3 m -1 μC at x = -0.1 m -1 μC at x = +0.1 m +1 µC at x = +0.3 m a) What is the value of the x-component of the electric field at points along the y-axis? b) What is the electric potential along the y-axis? (taking, as usual, the zero for potential at infinity.) c) Write the expression the work done in bringing this array together. You don't need to simplify the sum after writing it out, but you need to write out each term with relevant values and constants. (HINT: Note that there are six terms in the sum you need to do.) d) How does the potential approach zero in the limit as y goes to infinity? (That is, what functional form.) Justify why this is different than the form for a point charge, or even the "dipole" example done in class.

INSTRUCTIONS: Show your complete solution to each problem on a short bond paper. Answers must be expressed in engineering notation (when the exponent of the base 10 multiplier is not a multiple of 3, press ENG or SHIFT+ENG, whichever the case.) Example: 0.06N or 6.0x10-2 N must be expressed to 60x10-3 N or 60mN 5. At a corner of a 30 mm x 40 mm rectangle is placed a charge of -40µC and at the two adjacent corners are charges of +20µC, as shown in the figure. Determine: a. The potential at the 4h corner P. b. The potential at the center of the rectangle. c. The work that must be done by an external force to bring a charge q1 = +5µC from the center of the rectangle to the 4h corner P. 91 = +20 µC 92 = -40 µC в 30 mm P 40 mm 93 = +20 µC
Determine the magnitude of the vertical reaction (N) at A if P = 355 N and Q = 2100 N. Let x = 2.45 m, y = 2.56 m, and z = 2.06 m. Round off only on the final answer expressed in 3 decimal places. Instead of units, indicate the direction of the horizontal reaction at A: use R if to the right and L if to the left.
If quantity A is proportional to quantity B, describe how a graph of A vs B should look.
