Three point charges with q = 7.5 μC are located as shown. If L = 15 cm, determine the magnitude and direction of the total electric force acting on the point charge located at (0,−L).

Two charges, q₁=3.1 mC and q₂=1.6q₁ are placed along x axis so that q₁ is at the origin and 92 is at point (12.4, 0) cm. Where along the x axis is the net electric field equal to zero? Enter the x-coordinate of the position. Provide your answer in centimeters, with precision of three significant figures.

Problem 2. Three point charges are placed on the xy plane: (A) +50.0-nC charge at the origin, (B) -60.0-nC charge on the x axis at x = 1 0.0 cm, and (C) + 150-nC charge at the point (10.0 cm, 8.00 cm). Find the total electric force on the charge C and the electric field at the location of the charge C due to the presence of the +50.0- and -60.0-nC charges?

Two positive charges, each 4.18 µC, and a negative charge, -6.36 µC, are fixed at the vertices of an equilateral triangle. Calculate the length of the triangle side if the net electrostatic force on the negative charge is Fnet=29.6 N. Give your answer in SI units. Answer: Choose... +
