What is the formula of least count of spring balance?
Therefore, the minimum value it can measure is one hundred grams, which can be measured as follows: Measurement = 1 kg Total Number of divisions = 10 Least count= (1/10) = 0.1kg (or 100g) Hence 100g is the least count of this instrument.
How do you find the range of a spring balance?
Expert Answer:
- Least count of a measuring instrument is the least value of physical quantity that can be measured accurately using the instrument.
- For example,
- Take a spring balance whose range is 0-25kg.
- Measurement=1kg.
- Number of divisions=10.
- Least count=1/10 =0.1kg or 100g.
How do you calculate the least count?
Mathematically a measurement instrument Least Count is calculated by dividing main scale reading by the total number of divisions on the main scale. And if the instrument also has a Secondary scale. Then instrument LC is the ratio of main scale L.C. and number of divisions on the secondary scale.
What would be the least count of the spring balance used for measuring the force of range 0 1 KGWT and has total 100 divisions on its scale?
10 g
What is range and least count?
The least count is related to the precision of an instrument. Basically, An Ammeter has a range of 0−3A and there 30 divisions on the ammeter. Range is basically the difference between maximum value to the minimum value.
What is the least count of Screw gauge?
0.01 mm
What is the micrometer least count?
What is formula for total reading of vernier calliper?
Now find total reading using the equation, TR = MSR+VSR = N+(n x L.C) and apply the zero correction. Take the mean of the different values of the diameter and show that in the result with the proper unit.
What is vernier caliper least count?
0.02
What is the least count of scale?
Least count of a measuring instrument is the smallest measurement that can be made accurately with the given measuring instrument. A metre scale normally has graduations at 1 mm (or 0.1 cm) spacing, as the smallest division on its scale.
What is the unit of vernier scale?
Vernier scale is the sliding scale of the vernier calliper. It is the subsidiary scale provided for accurate measurement. The division on the vernier scale that coincides with the main scale reading is taken as the vernier scale reading. The value that we get as vernier scale reading does not have a unit.
What is the least count of 30 cm scale?
The length of an object was measured to be 30 cm by a linear scale of least count 0.1 cm.
What is the least count of Centimetre scale?
The size of the smallest division on a scale. For the main scale on the common vernier caliper this is probably 0.1 cm. With the vernier scale the least count might be 0.002 cm.
What is the least count of CM scale?
0.1 cm
What is the least count of 15 cm scale?
2) 1cm.
What is the least count of a ruler?
So the least count for a ruler is 1/10= . 1 cm or 1 mm. So with a ruler, the smallest dimension that you can measure is . 1 cm or 1 mm.
How do you calculate the least count on a tape measure?
Thus the measuring tapes can accurately measure 1/10 of an inch or 1 / 16 of an inch or 1/10 of a centimeter., which is the same as 1 millimeter. Depending on whether you use the tape to measure in inches or centimeters , the least count would be 1 / 10 of an inch or 1/ 16 of an inch or 1 millimeter ..
What is the least count of chain?
The least count of metric chain is 0.2m. The length of the link is the distance between the centers of the two consecutive middle rings. To enable the reading of fractions of a chain without much difficulty, tallies are fixed at every five – meter length for chains of 20m and 30m lengths.
What is a zero error?
zero error Any indication that a measuring system gives a false reading when the true value of a measured quantity is zero, eg the needle on an ammeter failing to return to zero when no current flows. A zero error may result in a systematic uncertainty.
What is the smallest division?
The smallest scale division is a tenth of a centimeter or 1 mm. Therefore, the uncertainty Δx = smallest increment/2 = 1mm/2 = 0.5mm = 0.05cm.
