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.ans is def B . how do i prove other parts are correct
,rotate
C is correct cuz of option B, A is correct cuz frictiom balances horizontal comp of MF so net force 0 so vel is const and cor D u can see i equated upward force > mg when cos(theta) is max which is 1
,rotate
Fm1 kuch torque nahi lagayega ??
Yss but iski value friction ke torqie ke barabar hogi
About com
So angular vel const
Asw as vel too
acha
v> mg/qB (1+costheta)
costheta = 1 kyu lia
Just for maximum purposes taki v ki max value pata lag jaye
alr
than
