guys can u pls help without use of hyperbolic cosine
@Gyro Gearloose
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.The string is in form of parabola
y²=4ax.
Radius of curvature at vertex of parabola is R=1/2a.
You need to find the value of a.
ayo what
i didnt get
parabola hai ACB is what he is saying. Have you studied parabolas? ( i dunno if it is or not I am going with what delu bhai is saying :D)
that eqn you see y² = 4ax is of a parabola
yo how do you type y²?
I just long pressed 2 lol
(Im on phone)
My b,are you a neet student?
haha nice
he moved to 11th rn
also why are they making you do tis for neet coaching?
dang hes fast ((or bro skipped idk))
When you derive a relation between forces you get a differential equation
The result of that happens to have a cosh term
So…it’s hard to avoid
Here is how you balance the forces
Physics Stack Exchange
Massive ropes and tension
Consider the diagram bellow, a massive string hanging in equilibrium
My question is this: Can we take any 2 random point on the rope, say A and B and then use $\sum F=0$ on the rope between them: ...
yes i understood that it is the equation of parabola but what am i to do with it sir
i feel like we can use centre of mass?
sir im doing this for myself(found this question somehwere) 😢 even this level is too much for neet?
lmao nah i started this early prep in like august september already
oh waw
Go for it, if your method is logical and it works, then you might be able to use that as a general method
wth i feel like neet is too easy-----i think the main difficulty comes in the competition and time management easy
Tis true. Mad competition yea
