Vernier Caliper and Screw Gauge

In an experiment with vernier callipers of least count $0.1 \mathrm{mm}$, when two jaws are joined together the zero of vernier scale lies right to the zero of the main scale and $6^{\mathrm{th}}$ division of vernier scale coincides with the main scale division. While measuring the diameter of a spherical bob, the zero of vernier scale lies in between $3.2 \mathrm{cm}$ and $3.3 \mathrm{cm}$ marks and $4^{\mathrm{th}}$ division of vernier scale coincides with the main scale division. The diameter of bob is measured as

The diagram shows the part of vernier scale on a pair of callipers. The correct reading is (least count $-0.01 \mathrm{cm}$)

A vernier caliper has its main scale of $10 \mathrm{cm}$ equally divided into $200$ equal parts. Its vernier scale of $25$ divisions coincides with $12 \mathrm{mm}$ on the main scale. The least count of the instrument is

The Vernier scale of a travelling microscope has $50$ divisions which coincides with $49$ main scale divisions. If each main scale division is $0.5 \mathrm{mm}$, then the least count of the microscope is

The zero of circular scale of screw gauge is hidden and ${95}^{\mathrm{th}}$ division of circular scale coincides with the baseline. Pitch $=1\mathrm{mm}$. $\mathrm{N}$ of circular divisions is equal to $100$. Then error is

A non-standard vernier calipers has $10 \mathrm{V}.\mathrm{S}.\mathrm{D}$ coinciding with $7 \mathrm{M}.\mathrm{S}.\mathrm{D}$, with each $\mathrm{M}.\mathrm{S}.\mathrm{D}$ equal to $1\mathrm{mm}$. The scale has a maximum measureable length of $100\mathrm{MSD}$. If ${14}^{\mathrm{th}}$ $\mathrm{M}.\mathrm{S}.\mathrm{D}.$ is found to coincide with $4^{\mathrm{th}}$ $\mathrm{V}.\mathrm{S}.\mathrm{D},$ where does the zero of vernier lie? Assume no zero error.

A screw gauge of pitch $1\mathrm{mm}$ has a circular scale divided into $100$ divisions and has no zero error. When the diameter of a wire is measured using this screw gauge, the main scale reading is $1\mathrm{mm}$ and the ${47}^{\mathrm{th}}$ circular division coincides with the main scale. The length of the wire is given as $5.6\mathrm{cm}$. The curved surface area of the wire up to the correct significant figures is

The pitch of screw gauge is $0.5 \mathrm{mm}$ and there are $100$ divisions on it's circular scale. The instrument reads $2$ circular divisions when nothing is put in between it jaws. In measuring the diameter of a wire, there are $8$ divisions on the main scale and ${83}^{\mathrm{rd}}$ division coincides with the reference line. Then choose the correct option (s).

The vernier of a vernier scale is divided into $10$ divisions which coincide with $9$ divisions of the main scale, each main scale division being $0.5 \mathrm{mm}$. When the two jaws of the instrument are in contact with each other, the $4^{th}$ division of the vernier scale coincides with a main scale division and the zero of the vernier lies to the right of the zero of the main scale. When a sphere is inserted between the jaws, the zero of vernier scale lies slightly to the right of $1.8 \mathrm{cm}$ and the $6^{th}$ vernier division coincides with a main division. The diameter of sphere will be
