Physics P1 and P2: Discussi0n

[Mobeen]

not kinetic to heat ..
potential to heat ..

 

[Waleed Asim]

It was POTENTIAL TO THERMAL(HEAT). How can you guys get it wrong? this was a repeat of a question of winter 2009 paper 2 Physics CIE -,- .

 

[Mobeen]

any chances of percentile droping low .. ?

 

[xcalibur]

For the first question of paper 2. I got the angle 22` but what was supposed to be the direction?
I wrote 22` North-East

 

[Mobeen]

wht was the answer to the mcq regarding the capacitor .. the direction of curent .. ?

 

[M@35TR0]

not kinetic to heat ..
potential to heat ..

Yeah potential to heat. Sorry.

 

[Jezla]

I think it was 1 and 3

I wrote 22` North-East

did we hav to write the angle ? i only wrote north east ..is tht corect ?

 

[Ab.R0xi0uS]

dude, A is MEGA! it was B!

Didnt we just have to write only the size and direction of the resultant???????

 

[Mobeen]

hey jezla i dont remember the the no.s .. . can u tell me was it frm + to - ..... or - to +

 

[xcalibur]

Yeah so direction is supposed to contain the angle i think..

 

[jafar]

wht was the answer to the mcq regarding the capacitor .. the direction of curent .. ?

it was the 2 aeros pointing 2wards the conventional current....

the resultant force was 460N
nd maybe ur direction (north east) wud be correct
em not sure though

 

[Mobeen]

dude, A is MEGA! it was B!

the answer was MW right ?

 

[Jezla]

Capacitor Question?

 

[Mobeen]

yep jezla ..

 

[Jezla]

This Question is a repeat..
Current anyways (conventional) flows from + to -
Therefore it had to be 1 and 3.

 

[knight101]

- to +(option D)

 

[Mobeen]

i dont understand it .. but i also did it - to + cuz in past pprs i was doin a capacitor question the answer was opposite the conventional curent.. in the case of capacitor only .. i dont know why this hapens but acording to mark scheme its - to +

 

[Mobeen]

wht was the resultant in q 1. i got 530 N
