The Total solution for NCERT class 6-12
A physical quantity┬аP┬аis related to four observables┬аa,b, c┬аand┬аd┬аas follows:
The percentage errors of measurement in┬аa,┬аb,┬аc┬аand┬аd┬аare1%, 3%, 4% and 2%, respectively. What is the percentage error in thequantity┬аP? If the value of┬аP┬аcalculated using theabove relation turns out to be 3.763, to what value should you round off theresult?
Percentage error in┬аP┬а= 13 %
Value of┬аP┬аis given as 3.763.
By rounding off the given value to the first decimal place, weget┬аP┬а= 3.8.
