An experiment measures quantities a, b, c and x is calculated from x = 
If the percentage errors in a, b, c are ± 1%, ± 3% and ± 2% respectively.
Text Solution
Verified by ExpertsThe correct answer is:
A
x = 
lnx = lna + 2lnb –3lnc
dx = 
da + 
db – 
× 100
× 100 = 
× 100 + 
× 100 – 
× 100
= 1 + 2 × 3 – 3 (–2)
Maximum error = ± 13 %
