The Total solution for NCERT class 6-12
A physical quantity P is related to four observables a,b, c and d as follows:
The percentage errors of measurement in a, b, c and d are1%, 3%, 4% and 2%, respectively. What is the percentage error in thequantity P? If the value of P calculated using theabove relation turns out to be 3.763, to what value should you round off theresult?
Percentage error in P = 13 %
Value of P is given as 3.763.
By rounding off the given value to the first decimal place, weget P = 3.8.
