(A) 2.5 micrometer
(B) 5.0 micrometer
(C) 10.0 micrometer
(D) 7.5 micrometer

A

2.5 micrometer

B

5.0 micrometer

C

10.0 micrometer

D

7.5 micrometer

Text Solution

Verified by Experts

The correct Answer is:
A
According to CPCB (Central Pollution Control Board) particulate size 2.5 micrometer or less in diameter (PM 2.5) are responsible for causing the greatest harm to human health.
These fine particulates reach to the lungs and causes respiratory problems, irritation, inflammation of lungs and may cause premature death.

Internal micrometer is a measuring intrument used to measure internal diameter (ID) of a large cylinder bore with high accuracy. Construction is shown in figure. There is one fixed rod B (to the right in figure) and one moved rod A (to the left in figure). It is based on the particle of advancement of a screw when it is rotated in a nut with internal threads. Main scale reading can be directly seen on the hub which is fixed with respect to rod B. When the cap is rotated rod A moves in or cut depending on direction of rotation. The circular scale reading is seen by checking which division of circular scale coincide with the references line This is to be multiplied by LC to get circular scale reading. Least count = value of 1 circular scale division = ("pitch")/("number of division on circular scale") Length of rod A is chosen to match the ID(PQ) to be measured. Zero error is checked by taking reading between standard blocks fixed at normal value of ID to be measured. Zero error is positive if cap end is one the right of the main scale and negative it is on the left side. In an internal micrometer, main scale division is of 0.5 mm and there are 50 divisions in circular scale. The least count of the instrument is-
