How was Physics paper 52?

[saima1995]

How was it guys? I found it relatively easy

 

[miss.insomniac]

what about the gradient?

 

[saima1995]

I found quite a large gradient, wasn't so hard to find though

 

[miss.insomniac]

quite large? took the power to -3 did you? for the values of x?

 

[nabeelah]

the paper was yummy

 

[mnotanerd]

quite large? took the power to -3 did you? for the values of x?

yes but still i got 8. something

 

[rabos1]

yes but still i got 8. something

I forgot to take power of x in -3, how many marks will they cut? I guess because of wrong power my gradient and error and everything got wrong.. no? paper was east though.. q1 was easy too.

 

[DumbIdiot]

what intercept did you guys get?

was it around 14 or was it a small number (less than one.....maybe negative)

it was negative and less than 1 whar did u get?

how did u forget??did you not see the values they gave on the graph paper..it gave a clear idea abt 10 -3

what did u kept constant on q1??frequeny or current??

 

[DumbIdiot]

what did u kept constant on q1??frequeny or current??

current, number of turns in coil and voltage

for question 2 y-intercept = -0.5

what about you?

 

[miss.insomniac]

what did u kept constant on q1??frequeny or current??

you dont keep frequency constant. thats the factor on which the height of the ring depends.

 

[miss.insomniac]

yes but still i got 8. something

mine was 6 for the line of best fit. 'not taking the power of -3' wont cost you much. i dont think so. its the ratio that counts.

i did the same mistake..and according to mark schemes i have seen till now the marks for gradient and intercept+ thier uncertainities all wld be deducted beacuse there is no place for e.c.f as we read the graph data incorrect..but they may award marks for finding k and v and d but that was jst worth 2\3 marks

 

[Aamer Faiyaz]

Did you guys get 8.3ish gradient?

Not possible. They'll cut one or two marks.. they'll see our method for errors and all.

Yeah I forgot to take power of -3, are you sure they won't cut so many marks? How many marks will they cut? Any idea?

 

[miss.insomniac]

so many? are you serious? :O

 

[miss.insomniac]

a maximum of 3:
-2 for the gradient and uncertainty thing
-1 for a wrong value of the constant. on that i doubt. marks cannot be deducted in the latter part of the question once it has been cut. what they emphasize on is the steps.
