1dunno the answer....method to batao kaise aaya wo....i don't hav the answer..sry about that [2]
1i m not sure, let me think
check with this;;
By cons of energy ω2=6g/L;
dm=(m/L) dx
Centrifugal force=∫dm ω2x (0 to L)
net force downward is mg+centrifugal force= 4 Mg
1You do not have any answer.It means that this problem has been framed by you.
1Two particles of mass m & 2m r fixed to a thin uniform circular loop of mass m & radius(15/11) cm at its diametrically opposite ends.The velocity of centre of the loop is v when it is in pure rolling. find the max. value of v so that the loop does not loose contact with the ground.
