Three charges are arranged in the (x,y) plane as shown. y (m) 10 9 8 7 6 5 4 8 nC 3 2 1 4 nC -6 nC 0 0 1 2 3 4 5 6 7 8 9 10 x (m) What angle does the resultant force on the 4 nC charge at the origin make with the pos- itive x axis? Quadrant I lies between 0° and 90°, quadrant II between between 90° and 180°, etc. Answer in units of °. Answer in units of °.
iii) Derive the expected mean count for a Poisson distribution. Prove that the average value of $v^2$ for Poisson distribution $P_\mu(v)$ is $\overline{v^2} = \mu^2 + \mu$. (HINT: Differentiate $\sum_{v=0}^{\infty} P_\mu(v) = 1$ twice w.r.t. $\mu$). Using this result, prove that the standard deviation of $v$ is $\sigma_v = \sqrt{\mu}$ (HINT: Use $\sigma_v^2 = \overline{v^2} - (\overline{v})^2$)
