Four charges are placed on the corners of a rectangle with length d = 0.00341 mm and breadth s = 0.00119 mm, as shown in the figure. The charges are given in terms of the elementary charge, e = +1.602×10‒19 C, as follows: q1 = q2 = +2000e and q3 = q4 = ‒3000e.
(a) Calculate the electric potential at point A, the middle of the rectangle, and at point B, the middle of the right-hand side of the rectangle.
(b) A particle with unknown charge q and mass m = 2.342 ×10‒20 kg is placed at point A, where it is initially at rest. The charge moves from point A to point B, where it has a speed of v = 12.23 m/s. Assuming that all forces apart from the electrostatic forces in the system are negligible, determine q. Use the answers obtained in (a) in your calculation.
(c) Would you be able to obtain the answer in (b) by using the equations of motion? Give a reason for your answer.

Four charges of magnitude +q are placed at the corners of a
square whose sides have a length d. What is the magnitude of the
total force exerted by the four charges on a charge Q located a
distance b along a line perpendicular to the plane of the square

Four identical point charges of magnitude q = 3.2 nC are placed
at the corners of a rhombus of edge length l = 22 cm and obtuse
angle θ. We intentionally leave θ undefined. Find the net electric
force on each of the four charges. Your answer will depend on the
angleθ. For convenience, orient your rhombus so that the charges
are placed at (±x, 0) and (0, ±y).
