Question

A wire of diameter 1 m m breaks under a tension of 1000 blank N. Another wire, of same material as that of the first one, but of diameter 2 blank m m breaks under a tension of

  1. 500 blank N  
  2. 1000 blank N  
  3. 10000 blank N  
  4. 4000 blank N  

The correct answer is: 4000 blank N


    Breaking force proportional to r to the power of 2 end exponent
    If diameter becomes double then breaking force will become four times i. e.1000 cross times 4 equals 4000 blank N
