Which of the following is the most precise device for measuring length: (a) a vernier callipers with 10 divisions on the sliding scale (b) a screw gauge of pitch 1 mm and 100 divisions on the circular scale
Added by Arun B.
Step 1
Given that the main scale smallest division is 0.1 cm and there are 10 divisions on the sliding scale. LC = Smallest division on main scale / Total divisions on sliding scale LC = 0.1 cm / 10 = 0.01 cm = 0.1 mm Show more…
