Field and force with three charges At a particular moment, one negative and two positive charges are located as shown in the figure. Your answers to each part of this problem should be vectors. It helps a great deal to make a diagram with arrows representing the various electric field contributions, and then check the signs of your components against these arrows. Let $Q_1 = 2\mu C$, $Q_2 = 7 \mu C$, and $Q_3 = -5 \mu C$. y $Q_1$ + A 1 cm $Q_2$ + $Q_3$ Part 1 Your answer is partially correct. (a) Find the electric field at the location of $Q_1$, due to $Q_2$ and $Q_3$. $\vec{E} = <$ 62.93 44.95 0 > N/C Save for Later Part 2 Your answer is partially correct. (b) Use the electric field you calculated in part (a) to find the force on $Q_1$.
The results of an inkblot test might be quite different when given to the same person on two different occasions. If this is the case, then based on this fact alone, the inkblot test is ? not reliable but probably valid ? not reliable ? not valid ? neither reliable nor valid
A thin-walled vessel of volume $V$, held at constant temperature, contains a gas which slowly leaks out through a small hole of area $A$. The outside pressure is low enough that leakage back into the vessel is negligible. (a) Show that the rate of decrease of the total number of particles $N$ inside the container is given by $\frac{dN}{dt} = -\frac{1}{4}n\bar{v}A$ where $n = N/V$ is the particle density in the container. (b) Use the equation of state of an ideal gas $\bar{p} = nk_BT$ to show that the rate of change of the pressure inside the container is given by $\frac{d\bar{p}}{dt} = -\frac{\bar{v}A}{4V}\bar{p}$ (c) Solve this equation and find the time required for the pressure to decrease to 1/e of its original value. Express your answer in terms of $A$, $V$ and the mean molecular speed $\bar{v}$.
