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

A charge Q is attached to each of two diagonally opposite corners of a square. A charge q is placed on each of the other two corners. a) If the resultant of the electrical forces acting on Q is null, what is the relationship between the charges Q and q? b) Could we choose a value of q such that the resultant on any of the other charges is null? Explain.

b) Calculate the net force (magnitude and direction) exerted on charge q by the other four charges, in terms of q, Q, d, and e0. You may draw the force vector to indicate the direction. c) If the charge q is released from rest, and the four other charges held fixed, will the charge q ever “escape” to infinitely far away (assuming an infinite amount of time can pass)? Justify your answer.
