Does the problem mean the oscillator is actually coupled but the expression for potential can be expressed in the form as if the oscillators were decoupled, but they are not practically decoupled ?

[@MridulSharma21]

Yes this is what it exactly means.

[@ahamadullahkhan4896]

what about coriolis and centrifugal force??? whats the connection b/w coriolis and centrifugal force with friction???

[@TarulataBaruah-t4q]

Sir in the first question since frame is rotating so there will centrifugal in outward direction therefore it slips.. Bcoz if there were friction it would have rolled... Isn't it sir... But sir if it slips doesn't this slipping impart any velocity??

[@nafeesaneelufer5023]

As the table is frictionless and rotating then centrifugal force will be acting which is not balanced. If there were friction motion because of centrifugal force of ball might be opposed and ball might have been at rest.

[@nargissultana5918]

Yes so eventually there must be a motion of the ball and hence linear velocity right? But the answer is given zero?🤔

[@tathagattripathi1203]

They just want the modal matrix(P) which we can easily get by finding out the eigenvectors of potential energy matrix V corresponding to coupled harmonic oscillator. these x and y are not normal coordinates here, rather x' and y' is normal coordinates.

Second question konse topic s th?

[@aranisa1]

Thank you !!

[@mittumitali1921]

Sir atomic and molecular physics ka please theory and previous yr questions solve kijiye

[@ShivaniSharma-wf7qy]

Sir gate 2021 kab upload kroge?

[@meenakshithakur245]

Sir Please is bar June me csir net ka jab exam hoga. Aur jab se bharna shuroo ho jayega tab mujhe message me send karna. Me interior type elake se hoon. Mere yahan facility ki shortage hai.

[@meenakshithakur245]

Mere pas aapke alawa koi source n hai.
