Note for OP
+solved @user1 @user2... to close the thread when your doubt is solved. Mention the users who helped you solve the doubt. This will be added to their stats.I am very confused as to how the mass of the lower block impacts the question
I'm not sure but both the block experience force by the springs. For an extension of x in spring of stiffness k, the lower block faces a force of 2kx towards left direction ig.
i think a got it but
its a bad method
Answer comes out to be 1 ig.
Oh CM doesn't shift. Crap I forgot that was a thing.
But how did you get the time period from the separate forces?
Force on the mass m is -3k(4x/3) (because both springs push in the same direction) So from this we can find time period. (Also to notice, x is inversely proportional to m and x is inversely proportional to k, so mass proportional to k and m/k is constant meaning you would get the same time period for the 3m mass)
Ok, so we take -4kx, but apply to the entire system mass which is 3m. That's what I didn't get.
Thanks.
