Solution

The correct option is A $1 c m$ , increasing no. of division
As the least count on this scale is $1 c m$ , so the scale can measure with an accuracy of $1 c m$ .
Accuracy can be increased by increasing the number of divisions on scale, i.e., by decreasing the least count of the scale.

A microsocpe is provided with a main scale graduated with 20 divisions in 1 cm and a vernier scale with 50 divisions of main scale. Find the least count of the microscope.

A microscope has its main scale with 20 divisions in 1 cm and vernier scale with 25 divisions, the length of which is equal to the length of 24 divisions of main scale. The least count of microscope is :

(a) 0.002 cm (b) 0.001 cm

Q. On the main scale of a travelling microscope

1 c m

is divided into 20 division ,What is the least count of the main scale of this device?

Consider the following data: 10 main scale division = 1cm, $10^{t h}$ vernier division match with $9^{t h}$ Main scale division. While measuring the zero error of the vernier we see that zero of vernier scale is to the right of the zero marking of the main scale with $6^{t h}$ vernier division coinciding with main scale divisions. The actual reading for length measurement is 4.3 cm with 2nd vernier division coinciding with main scale graduation. Estimate the length.
