Question

Three +3.0-μC point charges are at the three corners of a square
of side 0.50 m. The last corner is occupied by a -3.0-μC charge.
Find the magnitude of the electric field at the center of the
square. (*k* = 1/4*πε*0 = 8.99 × 109 N ∙ m2/C2)

Answer #1

Four equal +6.00-μC point charges are placed at the
corners of a square 2.00 m on each side. (k = 1/4πε0 = 8.99 ×
109 N ∙ m2/C2). Show your
work.

Consider a square which is 1.0 m on a side. Charges are placed
at the corners of the square as follows: +4.0 μC at (0, 0); +4.0 μC
at (1, 1); +3.0 μC at (1, 0); -3.0 μC at (0, 1). What is the
magnitude of the electric field at the square's center?

Three charges are at three corners of a rectangle with
side L1 = 7 m and L2 = 4.4 m as
shown below. If q1 = 1.1 μC, q2 =
4.7 μC, and q3 = -4.5 μC, what is the electric
potential (V) at the fourth corner? (Please note: the charge
is given in micro-Coulomb.)

Calculate the electric field (magnitude and direction) at one
corner of a square 1.22 m on a side if the other three
corners are occupied by 2.05 μC charges. Use as the
x-axis one of the sides of the square and give the
direction of the electric field in degrees measured anti-clockwise
from this axis.

Consider a square of side r = 4.60 cm with two q = +9.00 μC
charges at adjacent corners of the square and two p = −3.00 μC
charges at the other corners.
