AP Physics B FR: Form B

<p>I'm aware there were two forms..so here goes. Let's discuss form B. </p>

<p>How did you guys do the question with the ratios of the pressures??</p>

<p>And the one with charges..x.X</p>

<p>Ho yes, the first question, the graphing one. What did you guys graph and how?</p>

<p>for that one i think you would do D/T vs t cuause that velocity, and the velocity of the object linearly increases</p>

<p>for the charges part
a)
the charge vectors are to the bottom right of the +q charge, and to bottom left due to the +Q charge</p>

<p>b)(kQq/2x^2+2d^2)+(kQq/2x^2+2d^2)=2kQq/2x^2+2d^2 straight down from the +q charge</p>

<p>c) (Too lazy to do the rest of it but ill do it later)</p>

<p>FOr the ratio of pressures you could just plug in initial values and then do P1V1/T1=P2V2/T2 and solve for the pressures and then take the ratios as specified in the problem</p>

<p>i didnt take the Form B so just remember some of these answers may be wrong, I just did them in my head</p>

<p>Hey I have a question about Form B exams. When are they administered? Obviously they're different from the "late tests" that are given about 2 weeks after APs. Do international students take the Form B's? I don't understand... someone please enlighten me!</p>

<p>Oh, and is it just me, or after comparing the FRQs for the regular form and form B, doesn't the latter seem considerably easier??? AH! I feel that it's kind of unfair :( Oh well.... does anyone else agree?</p>

<p>Form A= Regular
Form B=International
Late= Neither Form A or Form B</p>

<p>and for AP Physics I didnt look at it VERY throughly but for this exam it seemed a little easier but that is very rare, usually Form B is harder</p>

<p>Mhmm, agreed. Thanks for confirming the whole form a and b thing, physicsrocks. :)</p>
