Answer #1

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 = 1/4πε0 = 8.99 × 109 N ∙ m2/C2)

Three +3.0 μC point charges are at the three corners of a square
of side 0.50 m. The remaining corner is occupied by a negative -3.0
μC charge. Find the magnitude of the electric field at the center
of the square. (k = 1/4πε0 = 8.99 × 109 N ∙
m2/C2)

Four point charges are located on the corners of the square with
the side of 40cm. Three charges are 1 μC and one is -1 μ C. Find
the electric potential at the center of the square (Assume that the
potential at infinity is zero)

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 point charges are located on the x-axis at the
following positions: Q1 = +4.00 μC is at x = 1.00
m, Q2 = +6.00 μC is at x = 0.00, and Q3 = -8.00
μC is at x = -1.00 m. What is the magnitude of the
electric force on Q2? (k = 1/4πε0 = 8.99 × 109 N
∙ m2/C2)

Two very small +5.0 μC charges are placed at
the ends of a meter stick. At the point 40
cm from the left side of meter stick,
Find (k = 9 × 109 N ∙
m2/C2) 1.1
A) Find the magnitude and direction of results of
electric force.
B) Find the results
of electric potential (relative to infinity).

Three point charges q1=1 μC ,
q2=2 μC and q3=-3
μC are located at three corners of a square of side a=2
cm . Charge
q3 is
located diagonally opposed to the empty corner of the
square.
Calculate the electric potential created by the three charges
at the empty corner of the square.
Calculate the work done by the electric field of the three
charges when a fourth charge q4=-4 μC
moves from the center of the square to the...

Four +10 µC point charges are at the corners of a square of side
11 m. Find the potential at the center of the square (relative to
zero potential at infinity) for each of the following
conditions.
(a) All the charges are positive
kV
(b) Three of the charges are positive and one is negative
kV
(c) Two are positive and two are negative
kV

The force of attraction that a -60.0 μC point charge exerts on a
+220 μC point charge has magnitude 5.00 N. How far apart are these
two charges? (k = 1/4πε0 = 8.99 ×
109 N ∙ m2/C2)

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.
a.)Find the electric field at the center of the square. Enter a
positive value if the electric field is straight down and enter a
negative value if the electric field is straight up. b.)Find the
potential at the center of the square.
