10- a) Derive time period of torsion pendulum and find an expression for modulus of rigidity of the material of the suspension wire.
OR
Differentiate the terms free, damped and forced vibration. Develop the differential equation of a particle executing damped vibration ina medium. Explain the physical meaning of each term and each constant in the equations.
- b) Categorise the wave according to the modes of vibrations and show = 6. that the intensity of a progressive wave is directly proportional to the square of its amplitude.
A worked answer is on its wayMeanwhile, read the Applied Physics notes for this topic.
