Q. 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. The zero error of the vernier callipers is

3 \times 10^{- x} c m

. Find the value of 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. 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).

Q. Let main scale division of a vernier callipers is 1 mm. With zero of vernier coinciding with the zero of main scale, the

division of vernier scale coincides with

49^{t h}

division of main scale. The least count of the vernier is

Q. The smallest division on main scale of a vernier callipers is

1 m m

10

vernier divisions coincide with

9

scale divisions. While measuring the length of a line, the zero mark of the vernier scale lies between

10.2 c m

10.3 c m

and the third division of vernier scale coincide with a main scale division. Determine the least count of the callipers.
