In this when we conserve angular momentum of bigger disc, why don't we add mr^2 (due to small disc) while writing moment of inertia of big disc, as the small disc is attached to the big disc

motor shaft is attached to circumfrence

#

small disc is not attached to bigger disc

narrow vigil
#

nvm bro i understood

vivid charm
#

so why do we need to apply the mr^2>

narrow vigil
vivid charm
#

nah

#

read ques

#

your in 11th?

narrow vigil
#

lemme check

vivid charm
#

come dms ill explain its a simple msitake

#

i also did it

narrow vigil
#

the motor is fixed to the disk bro

#

its given in the question

vivid charm
#

yes agreed

narrow vigil
#

however i know why we dont add mr^2

vivid charm
#

but why do we need to add mr^2to the disc?

narrow vigil
#

yeah i made a blunder

vivid charm
#

why?

narrow vigil
#

cause about the central axis the system is rotating with some omega

#

so about that axis i can write the angular momenta individually

#

for each body

#

if i am unclear then leave this doubt i asked something stupid

vivid charm
#

nothing is stupid man

#

genuine only

#

it odnt matter how others think

narrow vigil
#

real

#

thank you though

#

for acknowledging

#

the doubt

vivid charm
#

isme kya thank you

#

btw you solved?

#

the problem?

narrow vigil
#

yeah yeah

#

just conserve angular momenta

#

cause all torque is internal
