44) When finding the potential at the center, do this in 2 parts: first find the potential of
from the charges on the corners of the square, then find the potential from the charges
at the midpoints of each side.
a) For the charges at the corners of the square, what is the distance, rcorner, to the center
of the square? Find this in m, not cm.
corner =
m
b) What is the potential at the center of the square due to the charges at the corners?
Remember: V is a scalar, not a vector.
Vcorners =
_volts

srit a
c) What is the potential at the center of the square due to the charges at the midpoints
of the sides of the square? What is rmid, from the midpoints to the center? What is the
total V at the center? Remember: V is a scalar, not a vector.
Vsides =
volts
Vcenter =

d) How much work must be done to bring in a charge of 6e to the center of the square?
W6 =
Joules
