O 200m А B Useful information te = 1.60x10-19 C k9192 F. = 72 k=8.99x109 Nom trillion = 1012 G = ka E = (a). What kind of charge must the balloons be after you rub the balloons with sweater until each had gained some electrons, and why? (1pt) (b). Draw a picture showing how the balloons hang if both balloons are rubbed with sweater. (1pt) (c). What's the charges on the balloon A assume 200 trillion electrons are added to it? (2pts) (d). Draw a Free Body Diagram showing all the forces acting on balloon A. Be sure all forces are appropriately labeled. (3 pts) (e). The Balloon B is now removed from the vicinity of the balloon A such that it no longer has effect on the balloon A. To 3 sig figs, what is the magnitude of the electric field at the location where the balloon B used to be, about 20.0cm away from balloon A? You must show all work! Hint: Treat the balloon as a point charge now. Another hint: What will happen to the position of the balloon A when the balloon B is no longer near it?? (3 pts)
