How was 9702 w42?

can someone tell me what you did for the op amp part, and the last part of question 1 with the resistive force and radius?

Tbe op amp part was easy. U had to find potentials which i vot 2.5 and 3.178. In forces i wrote constant increase increase decrease

How did u get 2.5 and 3.178 ??

If there if

can someone tell me what you did for the op amp part, and the last part of question 1 with the resistive force and radius?

What did they ask you to find in that order again? I forgot

 

[Nushad Nahue]

And also the ratio of forces in the sphere and charged particle part? And there was this diagram with the electric field strength and magnetic field. what's the answer to that?

 

[Shujaat Khan]

Ratio 16 anyone? T_T i mean for radius one

Yes i got that

I found paper difficult, some part of questions were never seen in previous papers...
did u feel the same??

TSR friend.
Thanks.

Yes i got that

Yes me too. I always worry that my answers aren't correct if it's too straightforward cause there is always a twist somewhere

Yup even i have the same problem

Guys tell ur answers to question no. 1 last part

How did u get 2.5 and 3.178 ??

by using potential divider formula. At b it was resistance of lower in parallel it was 3 maybe divided by total and multiply by 6.

 

[salman9k]

Yes i got that

I got 16 as well

 

[Aqeeb Dange]

Yes i got that

Yess...even i got 16

Yea i did use the potential divider formula... nd for the first question of the op-amp... i got answer as 3.5V :/

Potential at point A or was it B? I think it should be zero when it's earthed but I'm not really sure about the Vout across the thermister when it was at a lower resistance.

alright wat abt the radon to air molecules ratio, i remember getiing 1.9 x 10^something

 

[manya]

wat was the natural frequency value in shm

Me too. It was a large value right?
