JEE MainPhysicsUnits and MeasurementsMCQ+4 / −1
One main scale division of a vernier caliper is equal to m\mathrm{m}m units. If nth \mathrm{n}^{\text {th }}nth  division of main scale coincides with (n+1)th (n+1)^{\text {th }}(n+1)th  division of vernier scale, the least count of the vernier caliper is :
  1. A
    1(n+1)\frac{1}{(\mathrm{n}+1)}(n+1)1​
  2. B
    m(n+1)\frac{m}{(n+1)}(n+1)m​
  3. C
    n(n+1)\frac{n}{(n+1)}(n+1)n​
  4. D
    mn(n+1)\frac{\mathrm{m}}{\mathrm{n}(\mathrm{n}+1)}n(n+1)m​
