Consider three point charges q1=q2=q3=Q. If q1 and q2 arelocated on the Y-axis at y=+a and y= -a and the third charge islocated at a point x on the X-axis. (a) find the force E exerted byq1 and q2 on q3 when q3 is located at the origin (b) what is theforce F on q3 when q3 is located at an arbitrary value of x on theX-axis? (c) for what value of x is the force F on q3 a maximum?Hint. The notation F means that you need to find the magnitude anddirection of the electric force.
