NEET PYQs for Units, Dimensions and Measurements with Solutions

1.
A student measured the diameter of a small steel ball using a screw gauge of least count 0.001 cm. The main scale reading is 5 mm and zero of circular scale division coincides with 25 divisions above the reference level. If screw gauge has a zero error of – 0.004 cm, the correct diameter of the ball is
- 0.521cm
- 0.053cm
- 0.525cm
- 0.529cm

In a Vernier caliper, \(N+1\) divisions of vernier scale coincide with \(N\) divisions of main scale. If 1 MSD represents 0.1 mm, the vernier constant (in cm) is:
- \(\frac{1}{10N}\)
- \(\frac{1}{100(N+1)}\)
- \(100N\)
- \(10N+1\)
