Question

If the thickness of the wire is doubled, then the breaking force in the above question will be

  1. 6 F    
  2. 4 F    
  3. 8 F    
  4. F    

The correct answer is: 4 F


    Breaking force proportional to pi r to the power of 2 end exponent
    If thickness (radius) of wire is doubled then breaking force will become four times
