Consider the diameter of a spherical object being measured with the help of a Vernier callipers. Suppose its 10 Vernier Scale Divisions (V.S.D.) are equal to its 9 Main Scale Divisions (M.S.D.) The least division in the M.S. is 0.1 cm and the zero of V.S. is at $\mathrm{x}=0.1\mathrm{cm}$ when the jaws of Vernier callipers are closed. If the main scale reading for the diameter is $\mathrm{M}=5\mathrm{cm}$ and the number of coinciding vernier division is 8 , the measured diameter after zero error correction, isNEET 2025
