Three charges are at the corners of an equilateral triangle, as shown in the figure below. Calculate the electric field at a point midway between the two charges on the x-axis. (Let q1 = 7.00 μC,
q2 = 9.00 μC,
and q3 = −3.00 μC.)
Three charged particles lie in the x y-coordinate plane at the vertices of an equilateral triangle with side length 0.500 m.
- Positive charge q2 is at the origin.
- Positive charge q1 is in the first quadrant, along a line 60.0°counterclockwise from the positive x-axis.
- Negative charge q3 is at (0.500, 0).

Three identical charges (q = −7.2 μC)
lie along a circle of radius 3.3 m at angles of 30°, 150°, and 270°, as shown in the figure below. What is the resultant electric field at the center of the circle?
Three negative point charges are located on the circumference of a circle of radius r centered on the origin of the x y-plane. Each point charge is labeled q. The charges are located at the following angular positions along the circumference.
- 30° counterclockwise from the +x-axis
- 150° counterclockwise from the +x-axis
- 270° counterclockwise from the +x-axis
