A positive charge Q₁ is placed a distance R to the left of a positive charge Q2 as shown in the figure. Both charges are held stationary. Point A is located a distance R3 to the right of Q1. A negative particle with a charge of -q and a mass m is placed at rest at a distance R2 above Q2. If the particle were to be released from rest, calculating its exact path would be a challenging problem. However, it is possible to make some definite predictions about the future motion of the particle. R A R What is the voltage at the initial location of the charge -q? Give your answer in terms of the variables in the question and Coulomb's constant k. The particle -q is released from rest and some time later it passes through point A. What is the voltage of at the position A (due to charges Q1 and Q₂)? Give your answer in terms of the variable in the question and Coulombs constant k. What is the kinetic energy of the particle -q when it passes through point A? Give your answer in terms of Vinitial, Vfinal, the charge -q. (Note: In the previous questions you found expressions for Vinitial and Vfinal, but in answering this question, simply use the variable names "Vinitial" and "Vfinal".) Vinitial V final KEtinal 4 R

1. What is cost effectiveness analysis(CEA)? 2. The following information has been gathered on the costs and effectiveness of the two treatments, A and B. In this problem, costs and consequences are not discounted. Treatment A Treatment B Mortality rate 2% 5% Life expectancy for survivors 20 years 10 years Initial treatment cost $10,000 $3,000 Follow up costs, year 1 $5,000 $1,000 Annual follow up costs, all subsequent years $1,000 $500 What is the total cost for the survivors receiving treatment A? For decedents (assuming sudden death)? What is the total cost for survivors receiving treatment B? For decedents? What is the expected cost for those patients receiving treatment A? Treatment B?

At the instant of the figure, a 6.20 kg particle P has a position vector $\vec{r}$ of magnitude 6.00 m and angle $\theta_1 = 48.0^\circ$ and a velocity vector $\vec{v}$ of magnitude 9.60 m/s and angle $\theta_2 = 30.0^\circ$. Force $\vec{F}$, of magnitude 3.60 N and angle $\theta_3 = 30.0^\circ$ acts on P. All three vectors lie in the xy plane. About the origin, what are the magnitude of (a) the angular momentum of the particle and (b) the torque acting on the particle?
