Arre, simple physics waala sawaal hai, yaar – jab lift upar jaati hai toh ek extra force lagta hai, isliye normal force bhi badh jaati hai, mg se zyada ho jaati hai. Par lift technician ki nazar se, main bolungi ki safai ke liye scale rakhne pe bhi weight badhta hai – ek baar lift ke floor pe thoda sa grease tha, scale thoda slide hui aur reading galat aayi! Isliye practical mein, it's never that perfect "mg" you read in books.
