What how? Isn't kinetic energy directly proportional to acceleration...and acceleration doesn't remain the same dies it?

Well force on the charge remains const. As electric field strength is constant, thus acc is const E=FS where E is kinetic energy and S is the disp from the negative plate

i had 2 under root 2

I think it was under root 2 cause the ratios if the diameters was 2 and that's as far as I got and I marked it as 2 :/

i just knew something was wrong

What was the answer for the diffraction grating double slit question where they asked which had greater separation between fringes and which was sharper?

 

[Snowysangel]

Ya your answer is correct (Y) I checked it cuz I still remember some qs

Noo my answer was 2 I realized that it was supposed to be root 2 further on in the paper and I didn't get time to correct it

Diffractij grating for both

Guys in question 37 about ldr and thermistor was the answerA low...low
And q38 is the only question I didnt have time for I just wrote D what was its answer

For the last three questions of radioactivity as far as I remember all three were B's. And I am pretty sure about it

 

[Rohan O]

And for the thermistor I guess it was low low don't remember the question exactly

 

[maryam fatima]

the paper made even a careless person like me to cry... so many calculation based questions... and calculations were also freaking tough.. i filled the answer sheet in last 15 seconds on which i had marked 5 to 6 options without even reading.... now just Allah's mercy can save us...

For the last three questions of radioactivity as far as I remember all three were B's. And I am pretty sure about it

ALL THREE WERE C'S AND IM 100 % SURE

 

[Princess Raven]

Did anyone get like a huge Lot of Cs.. And very few Ds

 

[beeloooo]

And for the thermistor I guess it was low low don't remember the question exactly

it was high for ldr and low for thermistor

 

[Princess Raven]

What did u all get for the current in X question and the one about which the escalator

 

[beeloooo]

Did anyone get like a huge Lot of Cs.. And very few Ds

maximum were C's expecially from 20-40

 

[beeloooo]

canu

What did u all get for the current in X question and the one about which the escalator[/quote

can u just remind the questions ?

 

[Princess Raven]

maximum were C's expecially from 20-40

Oh thank god! Kept getting Cs like even 4 Cs after each other

 

[beeloooo]

Diffractij grating for both

it was diffraction grating more space and less sharp . option C

 

[beeloooo]

Oh thank god! Kept getting Cs like even 4 Cs after each other

i remember 21-24 were C and the last three were aswell. the mcqs im kinda sure about

 

[Princess Raven]

Yea I chose c as well

it was diffraction grating more space and less sharp . option C

.

 

[Princess Raven]

The first ans was C and the last ans was c and between like 10 more Cs lol

i remember 21-24 were C and the last three were aswell. the mcqs im kinda sure about
