Modify Charge (Program} 3.2.1) so that the charge value \(q\) is not finat, and add a method increaseCharge() that takes a double argument and adds the given value to the charge. Then, write a client that initializes an array with

and then displays the result of slowly decreasing the charge value of \(a[i]\) by wrapping the code that computes the images in a loop like the following:

Charge[] a = new Charge [3]; a[0] = new Charge (0.4, 0.6, 50); a[1] = new Charge (0.5, 0.5, -5); a[2] = new Charge (0.6, 0.6, 50);
