A molecular physicist wishes to use the charges shown in Figure c to suspend a charged molecule for an experiment. Two positive charges, +0, 3: are used to keep the positively charged molecule from falling due to the +Q force of gravity (in the -y direction). The molecule can move on the y-axis. The mass of the molecule is m, the charge of the molecule is 1;, it can he Heated as a point charge, and the desired stationary position is 3'1" x i], 111, FT DI) (PS) What physical principles will you use to solve for the value of the charges +Q necessary to hold the molecule in place? +Q r = 4 E) (GR) Draw a Free Body Diagram of the molecule. Also, sketch a graph of the electric eld for points along the y-axis, E}, (y). (QA) Explain how these graphs show that it is possible to suspend the molecule using the two charges, +Q. Fig. 1: F) (AR) Solve for (derive) an equation for 32-2.}! (y). This is the total (net, resultant} electric eld due to the Q' s (not q) in the y-direction as a function of position along the y- axis. Your equation should be valid for -I s: y
