Solution

The correct option is B Vernier Calipers
$\begin{matrix} There are no main scales in a screw gauge So in the options only vernier callipers is the device which has combination of both main & vernier scale. \end{matrix}$

Q. A vernier caliper has no zero error, one main scale division =

1 mm

9

main scale division =

10

vernier scale divisions. A spring is held between jaws without exerting force on jaws. Main scale reading is

3.4 cm

, and 5th vernier scale division coincides with a main scale division. When jaws are pressed by force of

10 N

on both sides, main scale reading remains

3.4 cm

, but 1st division of vernier scale coincides with a main scale division. Now spring is removed, cut into two pieces and when inserted between jaws without any force, main scale reading =

1.1 cm

and 5th vernier scale division coincides with a main scale. If we apply force of

30 N

on both the jaws, main scale reading gets

1.0 cm

vernier scale division coincides with a main scale division. Find

^{'} x^{'}

Q. The least count of the main scale of a vernier callipers is

1 mm

. Its vernier scale is divided into

10

divisions and coincide with

9

divisions of the main scale. When jaws are touching each other, the

7^{th}

division of vernier scale coincides with a division of main scale and the zero of vernier scale is lying right side of the zero of main scale. When this vernier is used to measure length of a cylinder the zero of the vernier scale between

3.1 cm

3.2 cm

4^{th} VSD

coincides with a main scale division. The length of the cylinder is

(VSD

is vernier scale division

)

Q. The main scale of a vernier calipers is calibrated in mm and 19 divisions of main scale are equal in length to 20 divisions of vernier scale. In measuring the diameter of a cylinder by this instrument, the main scale reads 35 divisions and

4^{t h}

division of vernier scale coincides with a main scale division. Find radius of cylinder.

Q. Consider a vernier caliper. Least count of main scale is

1 m m

. There are 20 equispaced marks on vernier scale. When nothing is put between the jaws, zero of main scale lies between zero and first division of vernier scale and 15th division of vernier exactly coincide with one of the main scale division. When zero of vernier is matched with zero of main scale, 20th division of vernier exactly coincides with 25th division of main scale. To measure the side of a cuboid, it is kept between the jaws of vernier caliper, it is now observed that 18th division of vernier exactly coincides with 32th division of main scale. Choose the correct option(s).

A vernier callipers has its main scale graduated in mm and 10 divisions on its vernier scale are equal in length to 9 mm. When the two jaws are in contact, the zero of vernier scale is ahead of zero of main scale and 3rd division of vernier scale coincides with a main scale division. Find : (i) the least count and (ii) the zero error of the vernier callipers.
