Question:
The most precise reading of the weight of an object, among the following is
(1) 20 N
(2) 20.00 N
(3) 20.1 N
(4) 2.0×10¹ N
Answer:
(2) 20.00 N is the correct answer.
Explanation:
Whenever a measurement is taken by a measuring instrument it is seen that how much precisely it can measure it.
In the above question the more number of decimal places is having most precision.
The precision of something is measured by the closeness of two or more measurements on how close they are to each other.
Precision also tells how well an instrument can measure.
Answer:
20.00 N
Explanation:
Among the various options given in question statement, the correct option is 2nd.
The second option has data stored upto two decimal places, which means that the unit can be measured upto 1/100 of the single index. This also depends on the tool that is used and its least count, but the more the decimal places, the more precise the measurement gets
