Three point charges lie along a straight line as shown in the figure below, where q1 = 5.82 mu C, q2 = 1.60 mu C, and q3 = -2.18 mu C. The separation distances are d1 = 3.00 and d2 = 2.00 cm. Calculate the magnitude and direction of the net electric force on each of the charges. A point charge +2Q is at the origin and a point charge -Q is located along the x axis at x = d as in the figure below. Find a symbolic expression for the net force on a third point charge +Q located along the y axis at y = d. (Use the following as necessary: ke, the Coulomb constant, Q, and d.) Three charged particles are at the corners of an equilateral triangle as shown in the figure below. (Let q = 4.00 mu C, and L = 0.350 m.) Calculate the electric field at the position of charge q due to the 7.00-muC and -4.00-muC charges. Use your answer to part (a) to determine the force on charge q. Three point charges are aligned the x axis as shown in the figure below. Find the electric field at the following positions.
