v becomes root(2glsintheta)
then equate T=mgsintheta + mv^2/l
substitute T=2mg and you'll get answer
must have been some silly mistake or eq gaalt
v becomes root(2glsintheta) yeh kahan se aaya
conserve energy
Initial velocity consider nhi kri kya isme
2glsinq=v^2-25 is wht im getting🤔
whi toh initial vel bhi hai
can u check my process pls
updates..?
Process toh theek hi laga. 1/4 hi hona chahiye
But root(2glsintheta) toh initial velocity 0 hone par use karte hai na
yeah exactly
aight nice
@Real potato
Having u tried this?
yep
usi se sin inverse 1/4 aaya , phy galaxy says sin inverse 2/3
Ans galat dia ho skta h still ill try this on paper once
aight thanx
i have a few questions from phy galaxy which i believe galat solve kie hai
i also solve pg sometimes kafi ans galat mention kie gye hai so yeah it happens nothing to worry abt
Agar initial velocity ignore kr denge to aajayega ans Q=arcsin 2/3
so it is wrong
can i dm u with those questions or post em here ?

Two blocks each of mass M are connected to the ends of a light frame as shown in below figure. The frame is rotated about the vertical line of symmetry. The rod breaks if the tension in it exceeds T0. Find the maximum frequency with which the frame may be rotated without breaking the rod.
it could be or maybe im making some conceptual mistake
it probably is cuz someone else got 1/4 as well
ill recheck it
New thread please.
One q per thread
If you want a general discussion thread, please make it on the jee main thingy
If the main q was sorted please close this one out.
Oh yeah there is one mistake the last term will be 25/2 m first yaha se bhi sinq=1/4 ayega
toh 1/4 ✅ 2/3 ❌?
Can we close this please?
