divisions on the main scale of a vernier calipers coincide with divisions of the vernier scale. If each division of main scale is units, then the least count of the calipers is
- A
- B
- C
- D
Answer & Solution
Correct Answer
(C)
Step-by-step Solution
Detailed explanation
It is given that N+1 Divisions on vernier scaleV.S.D.=N Divisions on main scale M.S.D. ⇒ 1 V.S.D.=NN+1M.S.D. Least count of vernier callipers L.C.=1 M.S.D.-1 V.S.D. ⇒ L.C.=a-aNN+1=aN+1 unit
