Question

The time period of oscillation of a torsional pendulum of moment of inertia I is

• A. $T=2\pi \sqrt{I/k}$
• B. $T=2\pi \sqrt{I/2k}$
• C. $T=2\pi \sqrt{2I/k}$
• D. $T=2\pi \sqrt{I/4k}$

Answer 1

The correct option is A $T=2\pi \sqrt{I/k}$

The time period of oscillations of a torsional pendulum is $T=2\pi \sqrt{(}I/k)$
The correct option is (a)
