PhysicsHard156×since 2002Q8364One 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 :A1(n+1)\frac{1}{(\mathrm{n}+1)}(n+1)1Bm(n+1)\frac{m}{(n+1)}(n+1)mCn(n+1)\frac{n}{(n+1)}(n+1)nDmn(n+1)\frac{\mathrm{m}}{\mathrm{n}(\mathrm{n}+1)}n(n+1)mCheck answerSkip
