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 tried calculating net force on disc
But that doesnt seem to do much
any hints/approach?
Is the ans this?
Ill have to check but it was something like this only
Did it like this btw
Thanks
Ill check it out
I didn’t understand the part on the right side of the page.. why did you take d^2r/dt^2 negative
and did you neglect the delta r^2 term? In the (r+delta r)^2 term
Its cuz i wrote centrifugal force in negative accidently so to adjust i wrote d2r/dt2 negative
Ywa
The disc will accelerate inwards na
No look at rhe terms in mr*omega^2 and other one, since centrifugal one has rho prime which is greater thwn rho hence centrifugal one will be bigger so it will move outwards
@Real potato ok ?
Ill close it out tomorrow
