(ex part a) A positive point charge +4q is located at -d and a negative point charge -q is located at+d both on the x-axis, as shown on the diagram. A third point charge, +Q is to be placed at some other location x. What is the net electrostatic force on+ (due to the other two charges) as a function ofx in the regions: (a) -d<x <+d, (b) x>+d, (c) x<-d. Show detailed explanations and calculations for each. -t -d +d

D) in any of the three regions, is there a position x where the net electrostatic force on +Q is ZERO (due to the other charges)? Explain why or why not for each region.

E) Determine all of the values of x for which the net electrostatic force on +Q is ZERO. Show your calculation in detail.
