Two spheres of charge q1 and q2 that are equal in magnitude (i.e. |q1| = |q2|) are attached by a spring with a constant k = 1440kg/s2 and a rest length of x0 = 83.0cm. We take negative values of Äx for compression and positive Äx values for expansion. Knowing that q1 is positive and Äx = 4.40cm, what are the values of (a) q1 and (b) q2? If we know that q1 is negative and measure Äx = -3.50cm, then what are the values of (c) q1 and (d) q2? (hint for parts (c) and (d): take the magnitude of Äx under the square root sign and look at positive or negative roots for charges)
