Answer #1

Four point charges with magnitude 5.0 microcoulumbs are placed
at the corners of a square that is 30.0 cm on a side. Two charges,
diagonally opposite each other, are positive, and the other two are
negative. What are the magnitude and the direction of the force on
one of the charges?

A square with sides of length L has a point charge at each of
its four corners. Two corners that are diagonally opposite have
charges equal to 3.20 μC the other two diagonal corners have
charges Q. Find the magnitude and sign of the charges Q such that
each of the 3.20 μC charges experiences zero net force.

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?
