Answer 2

Answer:

The Torsional oscillations on a Torsional pendulum are due to restoring force in the wire is the correct statement.

Explanation:

• The physical pendulum's restoring force is gravity, as is the case with the basic pendulum. The centre of the pendulum bob is affected by gravity in the simple pendulum. The force of gravity acts on an object's centre of mass (CM) in the case of a physical pendulum.
• The motion of a torsional pendulum is periodic, oscillatory and angular simple harmonic. So, The Torsional pendulum executes linear Simple Harmonic motion is wrong statement.
• The time period of Torsional oscillations is not depends on twisting couple on a wire .
• The rotational kinetic energy of the disc is K = (1/2)IΩ² . The total energy must remain constant, except for frictional losses.
