Two parallel long (infinite for our purposes) wires are
suspended by a system of thin strings of length
L=3.2 cm each as illustrated in the figure below
showing the plane perpendicular to the wires. These wires are part
of the electric circuit and run the same (but unknown) current
I in the opposite directions. We treat the
current I algebraically assigning the positive
values to the current running out of the screen towards us (hence,
currents I and −I next...
Four equal charges q1 are situated at the corners of a square. The sides of the square are length a. 1) What is the net force on a charge q2 placed at the center of the square? 2) What is the electric potential at the center of the square? 3) Suppose one of four q1's is removed. Now whatis the net force on q2?
Two parallel long (infinite for our purposes) wires are suspended by a system of thin strings of length L=4.7 cm each as illustrated in the figure below showing the plane perpendicular to the wires.

Four point charges are fixed on the corners of a square as
shown. The square has sides of length 2l, with l= 0.05 m. The bottom two charges are equal in magnitude but
opposite in sign, Q1 and –Q1, with
Q1 = 1.2 microCoulombs, and the top two are equal in
magnitude but opposite in sign, Q2 and –Q2 as
shown, where Q2 = 2 Q1.If a charge of magnitude Q = 0.6 microCoulombs is placed in the
center of...
