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 getting 10^4
I think you cannot use MR^2 as moment of inertia that is the general formula it would be different based on the shape of the object
I just checked moment of inertia of a ring is 4/3MR^2
its a ring
isnt it mr2
when we rotate about center
Actually that is only of 3 spokes if we don’t know how many spokes there are it’s uncertain
That is ring question asks for wheel
we can assume ring to be wheel cant we?
Nope ig if it were the case your answer should be correct
this is what they did
Yeah I did this too
It’s fast and easy
.
what we do in this then
we still need I dont we?
Value of moment of inertia is given just use it as it is
wait nvm
i get it know
You changed moment of inertia to get it in terms of F
i accidently took it as mass
it will be solved now
With your method?
no need for writing that
i thought it was mass given
Oh
thats why i used MR^2
Yeah I was wondering that too
Ok nice
thx
