All charges are the same distance from the origin.
1) Without doing any calculations, does the electric field at
the origin in diagram 1 have a magnitude that is greater than, less
than, or equal to the magnitude of the field at the origin in
diagram 2? Justify.
2) If the distance between the charges and the origin is 6.1cm.
For each diagram shown, determine the magnitude and direction of
the electric field at the origin. (show calculations/equations)

Four point charges have the same magnitude of 2.4x10-12 C and
are fixed to the corners of a square that is 4.0 cm on a side.
Three of the charges are positive and one is negative. a) Determine
the magnitude of the net electric field that exists at the center
of the square (point P). b) Which of these charges, if released
from rest (while the others remain fixed), would pass through point
P? Explain
