Rod is massless? Then above solution doesn't makes sense, here i applied shm equations for the rod, about hinge,. It should be done with the block
Yeah , I was checking we have to find for block not rod @pratyaksh_tyagi bro, massless ki wajah force and torque same lagega
If rod is massless, then net torque will be 0
@pratyaksh_tyagi why did you take here x distance travelled by block as spring extension shouldn't it happen only when spring is fixed on one end here spring block and rod all have moved so we can't say this right ?
@Azimuddin_Sheikh can you elaborate ques 2 is rods massless....and is initially spring in natural length ?
Oh I was making a silly mistake , now got it thx a lot @Yash_Srivastava2 bro
i need following info for next one
Yup initially natural length and rods r not massless . Nvm I got the answer for the 2nd one now @Yash_Srivastava2 bro
This one is very tricky , anyone wanna give a try ??
Is it A ??
Nope everyone thinks of A , but actually different @Yash_Srivastava2 (hint : read the question again and see figure properly )
C right? Modified version of krotov question
Nice how u did it is more important than telling about the book @Chirag_Hegde bro ?? Also anyone interested in telling why answer is not 1 , as by the method of @Yash_Srivastava2 bro ?? Why can't we able to take components along the rope?? (I know the answer between if anyone want to know ) (but let's first other give their answers)
I am unable to figure out the question properly ... I mean It is written that the thread passes through another ring which moves with a constant velocity v ?
Where is the another ring in the diagram ?
@Azimuddin_Sheikh can u send a clear picture of the diagram
@Azimuddin_Sheikh mera toh A hi aa rha hai pta ni kyu pls send sol
Me too getting A
Wait I will send the pic by night and if needed solution tomorrow .
Ok send the diagram asap
