Consider the vernier callipers shown below. The instrument has no zero error. If 1 m.s. d = 1 mm and 7 m.s.d = 8 v.s.d, of the rod shown in the figure ? [ Given , the 4^(th) v.s.d coincides with m.s d ]

The zero error of the vernier calipers shown in the figure is _________.

A vernier calipers and a screw gauge have the same least count and zero error with the difference that the vernier calipers has positive zero error and the screw gauge has negative zero error. The number of circular scale divisions on the screw gauge is twice the number of vernier scale divisions on the vernier calipers and the pitch of the screw gauge is 1mm. If the vernier coinciding division and the circular are 3 and 97, respectively then find the number of vernier scale divisions on the vernier calipers.

Find the least count of the vernier caliper as shown in figure below. The main scale is in mm (i.e., 10mm, 20mm etc.)
