प्रश्न
State the formula for determining least count for a vernier callipers.
Advertisements
उत्तर
Least count (L.C.) = `"Pitch"/"No. of vernier scale division"`
For example: If the pitch is 0.1 cm and there are ten vernier scale divisions.
Then L.C. = `0.1/10` = 0.01 cm

External diameter of a tube
A screw has a pitch equal to 0.5 mm. What should be the number of divisions on its head so as to read correctly up to 0.001 mm with its help?
The circular scale of a screw gauge has 50 divisions. Its spindle moves by 2 mm on the sleeve, when given four complete rotations calculate
- pitch
- least count
A micrometre screw gauge having a positive zero error of 5 divisions is used to measure diameter of a wire, when reading on the main scale is 3rd division and the 48th circular scale division coincides with baseline. If the micrometer has 10 divisions to a centimetre on the main scale and 100 divisions on a circular scale, calculate
- Pitch of screw
- Least count of screw
- Observed diameter
- Corrected diameter.
How do you account for positive zero error for calculating the correct diameter of wires?
A measuring cylinder is filled with water up to a level of 30 ml. A solid body is immersed in it so that the level of water rises to 37 ml. Now the solid body is tied with a cork and then immersed in water so that the water level rises to 40 ml. Find the volume of the solid body and the cork.
What is the least count in the case of the following instrument?
