SIMPLE HARMONIC MOTION

Select the correct statements. (i) A simple harmonic motion is necessarily periodic (ii) A simple harmonic motion is necessarily oscillatory (iii) An oscillatory motion is necessarily periodic (iv) A periodic motion is necessarily oscillatory

A particle performing simple harmonic motion undergoes unitial displacement of (A)/(2) (where A is the amplitude of simple harmonic motion) in 1 s. At t=0 , the particle may be at he extreme position or mean position the time period of the simple harmonic motion can be

The equation of motion of a particle executing simple harmonic motion is a+16pi^(2)x = 0 In this equation, a is the linear acceleration in m//s^(2) of the particle at a displacement x in meter. The time period in simple harmonic motion is
