1. A spring with spring constant ks and rest length L has positive charges Q attached to either end, as shown. a) Find an equation that will determine the length D of the spring, once the charges have come to rest. D? b) Repeat part (a), this time assuming that the charges on either end are both negative. c) Repeat again, this time assuming that the charges on either end have opposite signs. *

B.) The charge of Sphere B will be net posiuve alnu tquai tu up C.) The charge of Sphere B will be net negative and equal in magnitude to Sphere A. D.) The charge of Sphere B will be net positive and less than Sphere A. E.) The charge of Sphere B will be net negative and greater than Sphere A. 8.) A student has set up the three circuits shown. The light bulbs and the batteries are identical. Ammeter A1 Battery A3 A2 Light bulb Rank all 3 ammeters (A1, A2, and A3) in order of their current measurements from greatest to smallest. A.) A1 = A2 = A3 B.) A1 = A2 > A3 C.) A3 > A1 = A2 D.) A1 = A3 > A2 E.) A3 > A2 > A1

What changes in the magnitude and the direction of the electric field would we witness if there is an increase in the voltage difference between the electrodes? a. The magnitude would increase only in the second investigation, but the direction would stay the same in both investigations b. The magnitude would stay the same in both investigations but the direction would change c. The magnitude would increase in both investigations but the direction would stay the same d. The magnitude would increase only in the first investigation, but the direction would stay the same in both investigations
