How was the Physics Unit 4 exam?

[saifulahmed49]

nope, I re-read the question multiple times as I had written initial to final, then corrected my mistake, what was your answer to acceleration of particle in electrical field?

did it using bq/m...don't remember the answer

 

[urwahboy]

you sure?can anyone else conform to this?

that was option D not C

 

[kcapfootball]

which MCQ option was it?

i think it was d

 

[aldamon]

did it using bq/m...don't remember the answer

you did it as a=EQ/m? I got a reeeaaallly high acceleration value :/

 

[urwahboy]

you did it as a=EQ/m? I got a reeeaaallly high acceleration value :/

lol i wrote the formula putted in the values then i read the qs gave the value of the speed... now i duno why dis they gave the speed , to confuse us? because that equation doesnt have speed in it... so i didnt calculated it just left it... if thats the corect formula (which u used) then i might get 2 marks for it...

yah...i think it was big...there was 10 to the power something

at first i thought what should i do with the speed, add it?multiply it?i didn't do anything...just thought i'm gonna fail this time, but actually the speed was needed to draw the graph

 

[urwahboy]

oh it was for the graph..i didnt get the graph how was i gonna use it anyway? haha

[aldamon]

well the graph would have gone with exponentially increasing velocity and then that velocity would have stayed constant if friction did not occur :/ I screwed up the graph too, but I'm getting all the answers now, was stressed during exams *sigh*

I got it about 2*10^6

 

[Believer]

It wasn't exactly 2*10^6 right?

Dont wprry every one screwed up the graph ..

it was 2.something *10^6. So what'd you get?

what about the tension graph, what'd you make of that? I made it like this --> ^ <---

 

[urwahboy]

i also made like but it was more of a curve not (^) like that

2.13*10^6 I don't remember exactly
