KCET 2025 | Units & Measurement and Dimensions Question 1 | Physics

The true length of a wire is $$3.678 \mathrm{~cm}$$. When the length of this wire is measured using instrument $$A$$, the length of the wire is $$3.5 \mathrm{~cm}$$. When the length of the wire is measured using instrument $$B$$, it is found to have length $$3.38 \mathrm{~cm}$$. Then, the

measurement with $$A$$ is more accurate and precise.

measurement with $$A$$ is more accurate while measurement with $$B$$ is more precise.

measurement with $$B$$ is more accurate and precise.

measurement with $$A$$ is more precise while measurement with $$B$$ is more constant.
