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

[rugged pine]

its a ring

[rugged pine]

isnt it mr2

when we rotate about center

[meager patrol]

Actually that is only of 3 spokes if we don’t know how many spokes there are it’s uncertain

[meager patrol]

That is ring question asks for wheel

[rugged pine]

we can assume ring to be wheel cant we?

[meager patrol]

Nope ig if it were the case your answer should be correct

[rugged pine]

this is what they did

[meager patrol]

Yeah I did this too

It’s fast and easy

[meager patrol]

.

[rugged pine]

what we do in this then

we still need I dont we?

[meager patrol]

Value of moment of inertia is given just use it as it is

[rugged pine]

wait nvm

i get it know

[meager patrol]

You changed moment of inertia to get it in terms of F

[rugged pine]

i accidently took it as mass

it will be solved now

[meager patrol]

With your method?

[rugged pine]

no need for writing that

i thought it was mass given

[meager patrol]

Oh

[rugged pine]

thats why i used MR^2

[meager patrol]

Yeah I was wondering that too

Ok nice

[rugged pine]

thx
