Question

Two holes of unequal diameters d1 and d2 left parenthesis d subscript 1 end subscript greater than d subscript 2 end subscript right parenthesis are cut in a metal sheet. If the sheet is heated

  1. Both d1 and d2 will decrease    
  2. Both d1 and d2 will increase    
  3. d1 will increase, d2 will decrease    
  4. d1 will decrease, d2 will increase    

The correct answer is: Both d1 and d2 will increase


    If the sheet is heated then both d1 and d2 will increase since the thermal expansion of isotropic solid is similar to true photographic enlargement
