Question

A smooth horizontal tube of length l rotates about a vertical axis as shown. A particle placed at the extreme end of the tube is projected towards 0 with a velocity l omega, while at the same time the tube rotates about the axis with constant angular speed omega. The path of the particle is given by

  1. r equals l e x p invisible function application left parenthesis omega t right parenthesis    
  2. r equals l e x p invisible function application left parenthesis negative omega t right parenthesis    
  3. r equals l e x p invisible function application open parentheses fraction numerator omega t over denominator 2 end fraction close parentheses    
  4. r equals l e x p invisible function application open parentheses fraction numerator negative omega t over denominator 2 end fraction close parentheses    

The correct answer is: r equals l e x p invisible function application left parenthesis negative omega t right parenthesis
