UNITS, DIMENSIONS & ERROR ANALYSIS TEST 1 1. Least Count of an instrument is Min. distance between two marks on the scale Minimum value which can measured by instrument Minimum value which can accurately measured by instrument None 2. Zero error is positive of vernier when Zero mark of vernier coincides with zero of main scale Zero mark of vernier lies towards left of zero of main scale Zero mark of vernier lies towards right of zero main scale. None 3. For a more accurate vernier callipers : L.C. should be more L.C. should be less accuracy does not depend on L.Count None 4. The measured value is Main scale reading + V.scale reading M.S. reading × L.C. + V.S. reading (M.S. reading + V.S. reading) × L.C. M.S. reading + V.S. reading L.C. 5. The –ve zero error is When zero watch with base line(B) (C) (D) when zero is above the base line when zero is below the base line None 6. The number of complete oscillations made by a vibrating body in one second is termed as velocity frequency displacement amplitude 7. The relation between frequency and time period of a vibrating body will be $T=v$ $T^{2}=v$ $T=\frac{1}{v}$ $T=v^{2}$ 8. S.I. unit of stress is $N/m$ $N/m^{2}$ $Nm$ $Nm^{2}$ 9. S.I. unit for Y is equal to Pressure Stress/strain Both None 10. Unit/units of specific heat is/are in S.I. the unit of specific heat is $JKg^{-1}K^{-1}$ in C.G.S. system, the unit of specific heat is cal $g^{-1o}C^{-1}$ (A) and (B) None of these Loading … Question 1 of 10
