Problem

The diameter of a cylinder is measured using a Vernier callipers with no zero error. It is found that the zero of the Vernier scale lies between

5.10\,\mathrm{cm}

and

5.15\,\mathrm{cm}

of the main scale. The Vernier scale has 50 divisions equivalent to

2.45\,\mathrm{cm}

. The 24th division of the Vernier scale exactly coincides with one of the main scale divisions. The diameter of the cylinder is
