physics paper 1,2 ........can we discuus da papper nw?

[plantaholic]

yayyy

 

[daredevil]

It was B i guess ,.,. the wires had to repel and then u can guess the direction of magnetic lines bu using the right hand rule

no no not that 1!! i am talking about the one in which there was a SINGLE electron shown and a grey area of magnetic field and we had to determine the direction of the electron beam. the one u r talking about is about 2 current carrying wires.

Downwards.

it was into the paper i think, so the beam deflected downwards

which question was this a part of? we had to write? right? or draw?

 

[17194]

It was in paper 1

mcq!!? what were the options?

 

[17194]

I don't remember all the options but it was something like upwards, downwards, into the page, or out of the page I think.

ok thanks

what the... people are confusing me I markd D was it correct conventional current one.. ??

i dont remember the correct option but it was the one with the conv arrow pointing right and elec one pointing left..

 

[pakiboy]

It was A. Centripetal force acting on the body acts towards the centre of the circle.

but by making vector diagram the ans was B!!!!!!! bcz a was downwards and b was towards the centre!!!!!!
there was no clue where the biker wanted to move................... no road direction he was just leaning on one side ...........

hy guys plz mark me..
qa) mas is the amount of mater contained by an object.
b)by subtracting the extended by original length...avoding parallax error and all that
Graph one was almost rite...no confusion with that
c)friction is a force that opposes,in newton....
d)Force 3800N
e)Ep=mgh..dnt remember the answer.
Change in state taking place,wrote about intermolecular foce
F)due to the presence of windows.
g)added up all the values.
h)I guess was about thermal energy which i did using formula mc(change in temperature)
i)warm air rises, cold being denser stays..ma.also drew a diagram ..
j)was about waves i gues......wrote about wave motion.......crest to trough.........hw it moves and alll that.
k)v=f*wavelength
l)pointed downwards.
m)5 cm far
n)from positive to negative....circular.......and one straight
o)i=q/t..bt dnt remember the value.

Section b
Q8)
drew a cicuirt with ammeter, voltmeter in parallel,batterires...and all that
using ammeter and voltmemeter to measure current and voltage.......metre to measure and length and using the formula R=v/I..to measure resistance.
Temperature directly propoertion ro resistance so incresing will afect the result..
Bt keeping the experimental conditions constat,carrying out the experiment in a same room,
pd was i thnk 2 or 3 v
Resitance inverse proportion to current...and gave a whole description..
resitance was i gues 16.somethng...did it ful working..

Q9)
alpha....heliem nuclied...frim radiactive decay....highest ionizing power....least penetrating power
Beta............fast moving electron.. al other thng
gamma........electromagneti waves, transverse in nature, shortest wanvelength.............
to carry out the experiment properly and was short in size...thts y the half life was less than few minutes...
alpha..present
gamma ...present
beta....no
from cosmos rays and burried rocks.........
may cause down syndrome adn blindness.....

When a body is moving in a circle, the resulting force and thus the resulting acceleration is towards the center of the circle.

Plz mark me for these question....

 

[17194]

vishal I don't remember all of it but F seems to be wrong. It was due to more thermal energy not windows. And in the radioactivity question, the question asked why a substance with a small half life was NOT used.

i dnt remember all the answers clearly....in F i thnk wrote it about thermal energy,,,,bt dnt knw about radioactivity,.....i gues i misunderstood the 1uestion....bt hw abt others?

See this Dude..........
I know its towards the centre of circle............

what is the 5 cm far question?
