Physics

A torsion pendulum is made from a disk of mass m = 6.6 kg andradius R = 0.66 m. A force of F = 44.8 N exerted on the edge of thedisk rotates the disk 1/4 of a revolution from equilibrium

1)What is the torsion constant ofthis pendulum?

2)What is the minimum torqueneeded to rotate the pendulum a full revolution fromequilibrium?

3)What is the angular frequencyof oscillation of this torsion pendulum?

4)Which of the following wouldchange the period of oscillation of this torsionpendulum?

A) increasing the mass

B) decreasing the initial angular displacement

C) replacing the disk with a sphere of equal mass and radius

D)hanging the pendulum in an elevator accelerating downward
