Question

For particle of a purely rotating body, v = r, so correct relation will be -

  1.   fraction numerator 1 over denominator r end fraction  
  2.  v  
  3. v  fraction numerator 1 over denominator r end fraction  
  4.  is independent of r  

The correct answer is:  is independent of r


    x2 + y2 = 2
    fraction numerator d y over denominator d t end fraction = – fraction numerator d x over denominator d t end fraction
     vA = – fraction numerator 4 over denominator 3 end fraction0
    Now, x =  cos 
    fraction numerator d x over denominator d t end fraction= –  sinfraction numerator d theta over denominator d t end fraction   = – open parentheses fraction numerator v subscript 0 end subscript over denominator l end fraction close parentheses
