L.C. \(=\frac{\text{Pitch}}{\text{Number of division on circular scale}}\)
\(\Rightarrow 0.01\,mm=\frac{\text{pitch}}{50}\)
\(\Rightarrow\) pitch \(=0.5\,mm\)
Mass = \( (28 \pm 0.01) \, \text{g} \), Volume = \( (5 \pm 0.1) \, \text{cm}^3 \). What is the percentage error in density?
The physical world includes the complications of the natural world around us. It is a type of analysis of the physical world around us to understand how it works. The fundamental forces that control nature are:
