Question

A particle is moving on a circular path of radius r with uniform velocity v. The change in velocity when the particle moves from P blanktoblank Q blankisblank left parenthesis angle P O Q equals 40 degree right parenthesis

  1. 2 v cos invisible function application 40 degree    
  2. 2 v sin invisible function application 40 degree    
  3. 2 v sin invisible function application 20 degree    
  4. 2 v cos invisible function application 20 degree    

The correct answer is: 2 v sin invisible function application 20 degree


    Change in velocity equals 2 v sin invisible function application open parentheses theta divided by 2 close parentheses equals 2 v sin invisible function application 20 degree

    A small mass m is attached to a massless string whose other end is fixed at P as shown in the figure. The mass is undergoing circular motion in the x minus y plane with centre at O and constant angular speed omega. If the angular momentum of the system, calculated about O blankand P are denoted by stack L with rightwards arrow on top subscript O end subscript and stack L with rightwards arrow on top subscript P end subscript respectively, then
