Question

State five precaution taken to ensure accurate result in experiment in principle of moments

Answer 1

Principle of moments -

According to the principle of moments, when a body is balanced about a point, then the total clockwise moment about a particular point is equal to the total anticlockwise moment at the same point.

Precaution is taken in an experiment in the principle of moments -

The five precautions taken to ensure an accurate result in an experiment in the principle of moments are -

1. We should avoid parallax error by placing both eyes at the measured level.
2. We should always switch the fan off to ensure no external environment interferes with the result.
3. We should always make sure that the ruler is well marked and has stopped its movement when the measurement is taken.
4. We should always note the observation accurately.
5. We should always read and record the point of the balance of the meter rule carefully.

Answer 2

Answer:

The Precaution that has been taken to accurate result in Principle of Moments.  

Explanation:

Principle of moments :--

According to the principle of minutes, if a body is the same at one point, then the total successive hours at that point are equal to the total consecutive time of the same point.

Caution: first balance the ruler used.

Caution: first balance the ruler used. Use pin distances greater than 25 cm (250 mm).

Caution: first balance the ruler used. Use pin distances greater than 25 cm (250 mm). Before using the ruler, evaluate the unknown and known weight in your hands and place the lighter mass as far away from the pin as possible.
