Question
For a torsional pendulum, the twisted wire exerts a restoring torque τ on the object that is proportional to its angular position θ. The relationship is given by:
Correct Answer
Option C is the correct answer.
Detailed Explanation
Equation (17) on page 10, under 'The Torsional Pendulum (Oscillator)', explicitly states: 'τ = -Kθ'.
Hint
The constant K is known as the torsion constant, analogous to the spring constant in linear SHM.
