Note for OP
+solved @user to close the thread when your doubt is solved. Mention the user who helped you solve the doubt. This will be added to their stats.First Equation:
$$ F{2} sin(\theta) = F{1} sin (30)$$
Second equation will be from the resultant
Keshav
Ok
Wait
Also try to form equation for F2 and then find its minima
cuz we have three variable and only 2 equations
So gotta use another relation
Bhai ye Kya Bol the ho ye to bahut tough lg rha mujhe to basic basic hi atta😭
@Keshav
Ye Kya bn gya😭
maxima minima nhi padha kya?
Vo to differentiation me hota Hai
(Ha padha Hai)
chal Let's go step by step now
$$ F{2} sin(\theta) = F{1} sin (30)$$
and,
$$ F{2} cos(\theta) + F{1} cos (30)=80\sqrt{3}$$
or,
Keshav
Is the answer 40√3

sorry If I made a mistake in writing somewhere
I am quite unwell today
Thanks a ton bro get weelll soon 🫂
Bro vese Mujhe kese PTA lgega Ki yha differentiation lgega
well yahan lga nhi
but kuch qs mei lg sakta
for example, minimum range waale qs (jb projectile padhega)
Practice ke saath samajh aa jaayega
bas ek acchi book use kar for supplement (theory)
Bro 1 month ho gya vectors basic hi nhi AA rhe phir aage kese ch start kru😭
Start krde
Qs bnate bnate aa jayega
and agar nhi aayega toh revisit kariyo lectures ko
tu kisi coaching mei hai?
PW
I am self struggling only
uh
I won't recommend it for Physics tbh
Hawa bahut hai but unke physics teacher ache nhi
Mai abj sir recommend krta
Aur syllabus track pe rakhne ke liye test deta reh
PW wasted my 6.6k
Vi Abhi BHI differentiation padha the basic vala
Test kese du?
bc
bhai abj sir se padhna start krle
ngl warna haalat kharab ho jaayegi
Cuz 11th physics is harder than 12th
Pw ke subscription ke saath mile honge na?
test series kuch na kuch toh?
Ha Mila hoga ig
Fr 17 inch ka dola is the worst
meanwhile, this guy 🗿 (adv se pehle saare ch ke pyqs daal diye)
I watch his lectures and they are awesome
No shit
No like kro sub kro
Not wasting even a single second like the BEE dablu
Free content but 10000x better than pw
chal bhai isko band krde agar doubt solve ho gya toh
Oh ha sry
Ek baar question try krleta hu
Bro Mera to ye aa rha
do a manipulation
divide numerator as well denominator by 2
\newline and use $sin(A+B) = sinA cosB + cosA sinB$
Keshav
Sin (a + b) kese lgau
$\frac{\sqrt{3}}{2} = cos 30 $
and $\frac{1}{2} = sin30$ (in degrees)
Keshav
Agya bro
and @Gaurav start with actual physics now, Physics mei itni manipulation sirf acche lvl ke qs mei aati
jo tu sikh jaayega cuz maths mei bhi yeh sab padhega acche se
MATLAB new chapter start krdu?(Rectilinear motion)
yes
agar basic calculus krli hai toh
itne vectors ke qs krne ki need nhi hai
Ok bro I had done basic calculus
And F1 kese nikalu resultant ke formula se?
use this equation (the first one)
Theta 60 hoga?
yes
cuz sin(30 + theta) jb max hoga tb F2 min hoga
And sin maximum 1 hota hai
here for theta = 60
Ok bro thanks a lot 🫂🫂🫂🫂🫂
