Question

Write 4 the instruments to measure the length and their presicion

Answer 1

Answer:

Correct option is

C

Screw gauge of least count 0.001 cm

The most precise instrument for measuring length is screw gauge

Least count of screw gauge =  

No. of divisors on circular scale

Pitch

 = 100

1.00mm

​=  1000 1 cm

=0.001cm

Answer 2

Answer: ✿

(C) Screw gauge of least count 0.001 cm ✔

Explanation: ✿

The most precise instrument for measuring length is screw gauge

Least count of screw gauge =

$\boxed{\sf{ \color{blue} \frac{Pitch}{No. of divisors on circular scale \: Pitch}}</p><p></p><p></p><p>}$

$\space$

$= \mathfrak{\frac{1.00mm}{100} = \frac{1}{1000}cm }$

$\bf{ \pink{ = 0.001cm}}$

Hope it helps!!
