Question

The three initial and final position of a man on the x minusaxis are given as
i) left parenthesis negative 8 m comma blank 7 m right parenthesis ii) left parenthesis 7 m comma blank minus 3 m right parenthesis and iii) left parenthesis negative 7 m comma blank 3 m right parenthesis
Which pair gives the negative displacement

  1. (i)  
  2. (ii)  
  3. (iii)  
  4. (i) and (iii)  

The correct answer is: (ii)



    (i) The displacement of the main from A blankto E is increment x equals x subscript 2 end subscript minus x subscript 1 end subscript equals 7 m minus open parentheses negative 8 m close parentheses equals plus 15 m directed in the positive x-direction
    (ii) The displacement of the man from E to C is increment x equals negative 3 m minus open parentheses 7 m close parentheses equals negative 10 m directed in the negative x-direction
    (iii) The displacement of the man from B to D is increment x equals 3 m minus open parentheses negative 7 m close parentheses equals plus 10 m directed in the positive x-axis
