1.	Whichof the followng relationships between the acceleration a and the displacement x of a particle involve simple harmonic motion? a= 0.7x.
Answer» Solution :There are two CONDITIONS for particle executes SHM. (i) Acceleration is directly proportional to displacement. Acceleration is always TOWARDS MEAN position `therefore " Acceleration " a= - omega^(2)x` `a= 0.7x` This given relation is not fit with `a= -omega^(2)x` hence it is not a SHM.
