Three charged particles are arranged on corners of a square as shown in the figure below, with charge -Q on both the particle at the upper left corner and the particle on the lower right corner, and charge +2Q on the particle at the lower left corner.

(i) What is the direction of the electric field at the upper right corner, which is a point in empty space?
a. It is upward and to the right.
b. It is straight to the right.
c. It is straight downward.
d. It is downward and to the left.
e. It is perpendicular to the plane of the picture and outward.
f. There is no direction; no field exists at that corner because no charge is there.
g. There is no direction; the total field there is zero

(ii) Suppose the +2Q charge at the lower left corner is removed. Then does the magnitude of the field at the upper right corner
a. become larger
b. become smaller
c. stay the same
d. change unpredictably
