[F] = [MLT ⁻ ²] [M] = [F] / [L][T⁻ ²] = [100N] / [10m][100s] ⁻ ² =10⁵kg.
Minimum inaccuracy = Vernier constant = 1 MSD – 1 VS.D = 1 MSD - 49/50 MSD = 1/50 (0.5mm) = 0.01
Minimum inaccuracy = Vernier constant = 1 MSD – 1 VS.D = 1 MSD – 49/50 MSD = 1/50 (0.5mm) = 0.01
If the unit of force is 100N, unit of length is 10m and unit of time is 100s. What is the unit of Mass in this system of units ?
[F] = [MLT ⁻ ²] [M] = [F] / [L][T⁻ ²] = [100N] / [10m][100s] ⁻ ² =10⁵kg.
[F] = [MLT ⁻ ²]
See less[M] = [F] / [L][T⁻ ²] = [100N] / [10m][100s] ⁻ ² =10⁵kg.
The vernier scale of a travelling microscope has 50 divisions which coincide with 49 main scale divisions. If each main scale division is 0.5 mm. Calculate the minimum inaccuracy in the measurement of distance.
Minimum inaccuracy = Vernier constant = 1 MSD – 1 VS.D = 1 MSD - 49/50 MSD = 1/50 (0.5mm) = 0.01
Minimum inaccuracy = Vernier constant
See less= 1 MSD – 1 VS.D
= 1 MSD – 49/50 MSD
= 1/50 (0.5mm) = 0.01
