HOMEWORK ANSWER 23 BECAUSE error is very large so it should be calculated by difference of area without error and area with error Acurate answer will be 23.21%
Option (D) 23 •/• ans This question can't be explained by error trick so Sol- l=1 so initial area is A= 1 We need to find final area to find ∆A As we see that length is increased by 11 percent so that Final l=1+11/100=111/100 So final Area=( final length)2. (Square) Final area= 111×111/100×100. =12321/10000 So ∆A= final area - initial area = 12321/10000-1 =2321/10000 = 0.2321 ∆A/A ×100=0.2321/1. × 100 = 23.21•/• Approx 23 •/• 😊so its my ans thankyou
I think the homework question was easy Ans (c) 22% Explanation : l = 1 , so delta l = 11% , as A = l^2 so, delta A/ A*100 = 2 (delta l/l *100) = 2(11%) = 22% I THINK ANSWER SAHI HOGA... I THOUGHT KUCH TO GADBAD HAI DAYA.. QUESTION ITNA EASY NAHI HO SAKTA. But, let's see if I get it correct or not. THANKS FOR THIS VIDEO SIR
Sir isme agar maximum area aur minimum area ko minus karke area se divide ➗ karke agar percentage error nikalenge to option se match nhi ho rha hai pls check
Thanks a lot again for these sessions❤...Now am feeling very confident on Errors😄 which wasn't before🤧...That Q. was doable for me....Thank you once again mam & sir❤️😊 Please bring toughest Q. of Fluid Mechanics🙏❤

HOMEWORK ANSWER
23
BECAUSE error is very large so it should be calculated by difference of area without error and area with error
Acurate answer will be 23.21%
That’s right
Option (D) 23 •/• ans
This question can't be explained by error trick so
Sol- l=1 so initial area is A= 1
We need to find final area to find ∆A
As we see that length is increased by 11 percent so that
Final l=1+11/100=111/100
So final Area=( final length)2. (Square)
Final area= 111×111/100×100.
=12321/10000
So ∆A= final area - initial area
= 12321/10000-1
=2321/10000
= 0.2321
∆A/A ×100=0.2321/1. × 100
= 23.21•/•
Approx 23 •/•
😊so its my ans thankyou
Are you sure ???
Mera bhi yahi aaya h
Pr sir ne sahi answer nhi bataya h
@@trushdevani153 pata nahi reply bhi nahi diye hai mujhe ese sahi lag raha hai
@@integrityineducation7597 muje bhi sahi lag raha h
Pr confirmation na ho tb tak doubt rehta h
Love the Energy!🎯🎯
@@UnacademyJEEkya sir ye sahi hai ya galat please reply 😊😊
Sir please define this question I can't understand that how it is so hard❤❤❤❤❤❤❤
Ans: 23%
Explanation : L(measure) = L(true) + L(true)×11%
Now, A(measure) = ( L measure)² = 111²/100² ×L(true) , now percentage error in A =111²/100²L(true)² - L( true)²/l(true)² ×100 = 23%
Good job!
Kha sir hame fasa nako koushis , A error se nahi hoga kyu ki 11% error is big error , hame grneral method se jana hoga
Ajj hi Sameer sir se iska derivation sikha and ajj hi adv ka question karliya maza aa gya
And hw question ka ans is opt-c 22%
Ans: D) 23%
Kudos!
Bring daily three advance que of three subjects it will help us alot
C option dA/A=2dL/L
Thankyou for this amazing session,
And thankyou for your support
Always welcome!!
23% by calculating change in area/actual area×100.
Good job!
Thanks alot sir for this wonderful session ❤❤❤❤
ans.22%
Always welcome
I think the homework question was easy
Ans (c) 22%
Explanation : l = 1 , so delta l = 11% ,
as A = l^2
so, delta A/ A*100 = 2 (delta l/l *100)
= 2(11%) = 22%
I THINK ANSWER SAHI HOGA... I THOUGHT KUCH TO GADBAD HAI DAYA.. QUESTION ITNA EASY NAHI HO SAKTA. But, let's see if I get it correct or not.
THANKS FOR THIS VIDEO SIR

A=l²
(Delta A)/A*100==2(delta l)/l*100
Implies %error in A ====c)22%
