The 50 ?? point charges are located on the x-axis. One is at ? = 1.00 ?, and the other is at ? =−1.00 ?. (a) Determine the electric field on the y-axis at ? = 0.500 ?. (c) Calculate the electric force on a −3.50 ?? charge placed on the y-axis at ? = 0.500 ?.

A positive point charge Q is located at x-a and a negative point charge -Q is at x = -a. A positive charge q can be placed anywhere on the y-axis. Find an expression for (FX, the x -component of the net force on q. Give your answer in terms of Q, q, a, y and constant K. Do your assessment by looking at (F)x when y = 0. net net

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?

Three charges are positioned at the corners of a parallelogram as shown above right. (a) If Q = 8.0 μC, what is the electric field at the unoccupied corner? (b) What is the force on a 5.0–μC charge placed at this corner?

A charge +q is located at the origin. A charge - 2q is at 3.15 m on the x axis. (a) For what finite value of x is the electric field zero? 7 Xm To the right of both charges, which charge is always closest? Does it have the smaller or larger charge? At what locations are there two field contributions that can cancel to produce zero net field? (b) For what finite value(s) of x is the electric potential zero? x m Because the charge of -2q is closer than the charge of +q for this value of x, the 2q dominates and the total field cannot be zero. m smaller value larger value

A 6 µC charge q1 located at the origin cm creates an electric field that fills all of space. A -8 µC charge q2 is brought to the point cm. The 6 µC charge is returned but now the -8 µC charge is moved to cm. What is the new net force extered on q2? Answer as a vector in Newtons.

A negative line of charge is on the negative y axis with its top end at the origin as shown in the figure below. The charge is uniformly distributed along the line. Point P is on the positive y axiS as shown in the figure. y The the length of the line of charge is 3.17 m, the total charge on the line is -787.9 nC and point P is 3.15 m from the origin. Find the magnitude of the electric field at point P due to the line of charge.
