Question

A particle starts from a point P at a distance of A/2 from the mean position O & travels towards left as shown in the figure. If the time period of SHM, executed about O is T and amplitude A then the equation of motion of particle is :

  1. x equals A s i n invisible function application open parentheses fraction numerator 2 pi over denominator T end fraction t plus fraction numerator pi over denominator 6 end fraction close parentheses    
  2. x equals A s i n invisible function application open parentheses fraction numerator 2 pi over denominator T end fraction t plus fraction numerator 5 pi over denominator 6 end fraction close parentheses    
  3. x equals A c o s invisible function application open parentheses fraction numerator 2 pi over denominator T end fraction t plus fraction numerator pi over denominator 6 end fraction close parentheses    
  4. x equals A c o s invisible function application open parentheses fraction numerator 2 pi over denominator T end fraction t plus fraction numerator pi over denominator 3 end fraction close parentheses    

The correct answer is: x equals A s i n invisible function application open parentheses fraction numerator 2 pi over denominator T end fraction t plus fraction numerator 5 pi over denominator 6 end fraction close parentheses
