density \( \rho = \frac{m}{V} \) hai, toh percentage error formula lagayi jaati hai: \[ \% \text{ error in } \rho = (\% \text{ error in mass}) + (\% \text{ error in volume}) \] Yad rakhna, dono errors add hoti hain kyunki volume denominator mein hai. Mera practical file banaate waqt pata chala — jab papa ne purane zameen ka rava (mass) aur aayaat (volume) naapne mein thoda approximation liya tha, tab bhi aisa hi formula laga kar final galti nikaali thi. Isi liye yaad rahega!
