1 micrometer= fm...

`1 micrometer= __ fm`

Text Solution

Verified by Experts

The correct Answer is:
`=2pisqrt(m/(2k))`
`a`. Suppose the particle is pushed lightly against the spring C through displacement x.
Total resultat force on the particle ils kx.
Due to spring C and `(kx)/2` due to spring A and B.
`:.` Total Resultant force
`=kx+sqrt((kx)^2/(sqrt2)^2)+(kx)^2/(sqrt2)^2`
Acceleration `=(2kx)/m`
`Time period =2pisqrt((displacement)/((Ac cel eration))`
`=2pisqrt(x/(2kx/m))`
`=2pisqrt(m/(2k))`
[Cause: When the body pushed against C the spring C tries to pulll the block XL. At that moment the spring A and B tries to pull the block with force `(kx)/sqrt2 and (kx)/sqrt2` respectively towards xy and xz respectively. So the total force on the block is due to the spring force C as well as the component of two spring force A and B.

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-
