Question

Statement 1: When an automobile while going too fast around a curve overturns, its inner wheels leave the ground first
Statement 2: For a safe turn the velocity of automobiles should be less than the value of safe limit velocity

  1. Statement 1 is True, Statement 2 is True; Statement 2 is correct explanation for Statement 1  
  2. Statement 1 is True, Statement 2 is True; Statement 2 is not correct explanation for Statement 1  
  3. Statement 1 is True, Statement 2 is False  
  4. Statement 1 is False, Statement 2 is True  

The correct answer is: Statement 1 is True, Statement 2 is True; Statement 2 is not correct explanation for Statement 1


    When automobile moves in circular path then reaction on inner wheel and outer wheel will be different
    R subscript i n n e r end subscript equals fraction numerator M over denominator 2 end fraction open square brackets g minus fraction numerator v to the power of 2 end exponent h over denominator r a end fraction close square brackets and R subscript o u t e r end subscript equals fraction numerator M over denominator 2 end fraction open square brackets g plus fraction numerator v to the power of 2 end exponent h over denominator r a end fraction close square brackets
    In critical condition v subscript s a f e end subscript equals square root of fraction numerator g r a over denominator h end fraction end root
    If v is equal or more than the critical value then reaction on inner wheel becomes zero. So it leaves the ground first
