Question

Three equal positive point charges of magnitude Q = 9.00μ C are located at three corners of a square of edge length d = 8.1 cm. A negative charge -27.00μ C is placed on the fourth corner. At the position of the negative charge, what is the magnitude of the electric field due to the three positive charges?

Three charges, each of magnitude 6 nC, are at separate corners
of a square of edge length 4 cm. The two charges at opposite
corners are positive, and the other charge is negative. Find the x
and y components of the force exerted by these charges on a fourth
charge q = +3 nC at the remaining (upper right) corner. (Assume the
+x axis is directed to the right and the +y axis is directed
upward.)

square. (k = 1/4πε0 = 8.99 × 109 N ∙ m2/C2)

There are four charges, each with a magnitude of 1.91 μC. Two
are positive and two are negative. The charges are fixed to the
corners of a 0.266-m square, one to a corner, in such a way that
the net force on any charge is directed toward the center of the
square. Calculate the magnitude of the net electrostatic force
experienced by any charge.

Four equal negative point charges are located at the corners
of a square, their positions in the x-y plane being (1, 1), (-1,
