You will modify a shell program to calculate the motion of a charged particle in a region of space where there is an electric field due to an electric dipole. Recall that a dipole is constructed from two equal magnitude, opposite sign charges (q) separated by a distance s. You will be given a shell program that contains the location and charge of the dipole. You will have to write a loop that does several things in order: 1) it computes the electric field caused by the dipole at the location of the moving particle, 2) it uses the momentum update formula (Newton's 2nd law) to find the change in momentum caused by the impulse from the electric force on the particle after a short time interval, 3) it uses the position update formula to determine how the particle will move in a short time step. Then the loop will repeat these calculations starting at the new particle location. After following the motion for some assigned time, you will input the final value of the particle location and velocity for credit.
