Question

There are four charges, each with a magnitude of 2.18 µC. Two are positive and two are negative. The charges are fixed to the corners of a 0.21-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. Find the magnitude of the net electrostatic force experienced by any charge.

Answer #1

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.

Identical point charges of +1.2 µC are fixed to three
of the four corners of a square. What is the magnitude |q| of the
negative point charge that must be fixed to the fourth corner, so
that the charge at the diagonally opposite corner experiences a net
force of zero?
|q| = Number _______ Units _____

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.)

Four particles each
have a positive charge of 6.00 x 10-16 C. The charges
are arranged on the four corners of a square that is 25.0 cm on a
side. What is the net force experienced by the particle located on
the bottom-left corner of the square?
