Thanks for the help guys... I appreciate it so much :D Finally I solve this problem lol

Ah i see...Now I understand that my equation is wrong... It must be T=W+Fcentrifugal T=mg+mv^2/r T=mg+m(omega)^2 L Now, how do i change the omega ? Thanks guys for your helps...

That's my problem.. i don't understand well about the centripetal force.. am i right if i draw the centripetal force in the same direction as T? So my equation will be Fy=0 T=W-Fs Also when does we use the centrifugal and when does we use the centripetal one? Thanks for all

At first, I think that the tension string will be the same as the Weight, so i answer T=mg, but the answer key is T=2mg. So, I start to think about the centripetal and centrifugal force... but still I don't have any idea to solve it.. Is my idea about the centripetal and centrifugal is correct?

My name is Nicholas, and I still learn physics.. Thanks
