<p>I’m SOOOOO glad I decided not to put off Physics C studying until this weekend; it helped since my teacher only spent 2 days on magnetism and not enough on electric stuff.</p>
<p>I did the sphere problem correctly at first and then went back and changed all my answers. DAMN IT.</p>
<p>Probably missed 15-20 on MC. Did very well on four of the six FRQs and failed epicly at the other two. Sphere in a vacuum chamber, wth?</p>
<p>in the bargaining phase?</p>
<p>How many of you gave up and said to use the ruler to measure the distance?</p>
<p>Also, the 2nd sphere doesn’t affect anything, since it has no charge, right?</p>
<p>
</p>
<p>I think that’s what you were supposed to do.</p>

<p>V inside the ball=V on edge of the ball, which is just kQ/r</p>
<p>I was soooo tempted to put “Use the ruler, stupid…” But this i noticed they asked for something else. I was like OH I KNOW!</p>
<p>Seahawks-we shouldnt try to talk about this on the forums till the ban is lifted. ill send u an private message</p>
<p>Edit: someone already posted as I typed this XD</p>
<p>r = distance away from sphere center or distance away from surface?</p>
<p>@JamesGold: If so, they’re *******s for making that question…</p>
<p>Also, I don’t think so, since they had follow up questions about how something should happen if you change d.</p>
<p>mλL/x= d, so increase d and x decreases, so the peaks were closer together?</p>
<p>
</p>
<p>Yeah that’s what I said</p>
<p>was the work on the first one negative or positive?</p>
<p>negative because the force opposed the object’s motion</p>
<p>Did you guys use the edges of the strips as “slits”?</p>
<p>Well, what else could you have used?</p>
<p>Wait, in the formula, “d” is the distance between the slits…</p>
<p>the filament light bulb? lol</p>
<p>sigh that lab question was such a ■■■■■, collegeboard is becoming more and more ■■■■■ every year</p>
