1. a faraday ice pail similar to the one you will use in the experiment is used in this question. the principle of its operation relies on the proportionality between the charge on the inner pail and the potential difference between the inner pail and ground. suppose the relationship between charge q and potential difference � is given by � = � ∙ 4.30×10jz . when a charged wand is inserted into the inner pail and touches it, the electrometer reading is −16.0 . (a) how much charge resided on the wand? (b) before grounding the pail, a second wand is inserted into the ice pail and touches it. the electrometer reading now is +28.0 . how much charge resided on the second wand? (c) if the two wands were separated by 7.50 �� before they were discharged onto the ice pail, what magnitude of force did either exert on the other? was it attractive or repulsive? assume that no leakage of charge occurs during the experiment and that charge on the wand is same as the charge on the pail. recall that j ^_`a = 9.00×10c ��e �e .

russian is not my first language, so i'm afraid i can't write out an answer in russian, but hopefully you can find a way to do so. here's my best translation of the problem: you're given a plot of a particle's position in one-dimensional space over time, and you're asked to find either the total distance traveled by the particle after 6 seconds had elapsed, or the total displacement of the particle after 6 seconds.

if you want the total distance traveled, you would first need to determine the particle's velocity as a function of time, then integrate that over the 6-second interval. we know the position function is quadratic with roots at 0 and 6, so we have

where is unknown. because the position is parabolic, there is symmetry about the midpoint at , and we know that

so that the position function is

which means the velocity is

then the total distance traveled is

so the total distance traveled is 20 m.

on the other hand, if you want to find displacement: the particle starts at and ends at , so its displacement is 0.
