If \(P, Q\) and \(R\) are physical quantities having different dimensions, which of the following combinations can never be a meaningful quantity?
A cylindrical wire has a mass \((0.3 \pm 0.003) \mathrm{g}\), radius \((0.5 \pm 0.005) \mathrm{mm}\) and length \((6 \pm 0.06) \mathrm{cm}\). The maximum percentage error in the measurement of its density is
The Vernier scale of a travelling microscope has 50 divisions which coincides with 49 main scale divisions. If each main scale division is \(0.5 \mathrm{~mm}\), then the least count of the microscope is
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
