<p>escius- I got 4 As in a row (the last one was on the next page).</p>
<p>what'd guys put for the one with 3 charges (+,-,+) and which one feels being pushed to the left? I think I said only -</p>
<p>I really don't know, sorry. For the question with the two charged bars, did the particle make a cyclic path around the upper bar?</p>
<p>yes, right one</p>
<p>wasnt it parabolic?</p>
<p>pendulum changes with the period, I am 100% sure. I think T/2</p>
<p>I figured if it goes up, it will be attracted to the upper bar and thus make a circle. Not sure; I just figured it that way.</p>
<p>but arent elctric feidls parabolic</p>
<p>I dunno. I've never heard it before, but could easily be right.</p>
<p>def parabolic since the elect4ic force is always vertical, it doesnt change with the particle velocity</p>
<p>I dunno. Anyone else wanna weigh in on this?</p>
<p>i looked in my text, acceleration doesnt point to the center,so its just like free fall curves</p>
<p>Darn. Another one wrong; up to 3 skip and 8 wrong...Was the astroid one the astroid was the longest?</p>
<p>yes, that test was much harder than the read sat2s book</p>
<p>Yes to the astroid? Good. So you think the curve will be more leineient?</p>
<p>theres a strange trend, everyone always thinks the test they took was harder.</p>
<p>Okay, your probably right. For the question about when the one motion equation would work, was it the one on flar surface?</p>
<p>oo yea what was that x= xknot +vknott + 1/2at^2 one??</p>
<p>oops, period was 2T</p>
<p>canucksource, yea. Is it B., the flat one?</p>
<p>yes it is b</p>
