Homework Statement
A meter stick is hung at its center from a thin wire. It is twisted and oscillates with a period of 6.0 s. The meter stick is sawed off to a length of 70.0 cm. This piece is again balanced at its center and set in oscillation.
Homework Equations
T = 2PI / (omega) = 2PI * (sqrt(I/k)) where I = m.o.i and k =torsion constant
The Attempt at a Solution
I managed to get the value for the two period
T = T_0 * sqrt (I / I_0) where T_0 and I_0 are the initial parameters. The problem is the question does not state the I and I_0. I tried considering it to be a thin rod but failed. The correct answer is 3.5s.
