At a certain distance from a charged particle, the magnitude of the electric field is 518 V/m and the electric potential is -3.20 kV. (a) What is the distance to the particle? m (b) What is the magnitude of the charge? $\mu$C Need Help? 8. [0/10 Points] DETAILS PREVIOUS ANSWERS SERPSE10 24.3.OP.014.MI. The three charged particles in the figure below are at the vertices of an isosceles triangle (where $d = 2.80 \text{ cm}$). Taking $q = 6.70 \,\mu C$, calculate the electric potential at point A, the midpoint of the base. Superposition allows us to determine the electric potential due to each charge and then sum them to find the total electric potential, $V$.

Consider a particle in the ground state of an infinite square well of width $L$, with its full wave function at time $t=0$ given by $\Psi(x,0) = \sqrt{\frac{2}{L}} \sin(\frac{\pi}{L}x)$ if $0 \le x \le L$, and equals zero otherwise. Calculate $<x>$, $<x^2>$, $<p>$, $<p^2>$, the uncertainty in $x$: $\sigma_x$, the uncertainty in $p$: $\sigma_p$ (all at time $t=0$). Check that your results are consistent with the uncertainty principle. Do any of the averages you calculated change with time?

As part of a circus act, a person drives a motorcycle with constant speed $v$ around the inside of a vertical track of radius $r$, as indicated in the figure (Figure 1). The combined mass of the motorcycle and rider is $m$. Part A Find the normal force exerted on the motorcycle by the track at the point A. Express your answer in terms of some or all of the variables $m$, $v$, $r$, and appropriate constants. $N_A = $ Part B Find the normal force exerted on the motorcycle by the track at the point B. Express your answer in terms of some or all of the variables $m$, $v$, $r$, and appropriate constants. $N_B = $ Part C Find the normal force exerted on the motorcycle by the track at the point C.

(4) [40 marks] Suppose we have an election between 3 candidates A, B and C. Since all the candidates are quite bad, the voters vote randomly between the 3 candidates with probabilities $P_A$, $P_B$ and $P_C$ ($P_A + P_B + P_C = 1$). Assuming that there are $n$ independent voters and let $Y_A$ be the random variable equal to the number of votes candidate A receives. • What is the distribution of $Y_A$? Calculate $E[Y_A]$. [5 marks] • Let us define the joint distribution $PDF_{Y_A, Y_B, Y_C}$. For $i$, $j$, $k$ such that $i, j, k \in [0, n]$ and $i + j + k = n$, calculate $PDF_{Y_A, Y_B, Y_C}[i, j, k]$. [15 marks]. • If $P_A = 0.2$, $P_B = 0.3$ and $P_C = 0.5$ and $n = 8$, calculate the probability that A receives half the votes and candidates B and C receive a quarter of the votes each. [5 marks]. • In this same scenario, compute the probability that A receives 3 votes. [5 marks]. • In this same scenario, if A receives 3 votes, compute the probability that B and C receive 3 and 2 votes respectively. [5 marks]. • If A receives 3 votes, calculate the expected number of votes that B receives? [5 marks].
