To estimate ‘g’ (from g = 4π 2 
), error in measurement of L is + 2% and error in measurement of T is + 3%. The error in estimated ‘g’ will be –
Text Solution
Verified by ExpertsThe correct answer is:
A
g = 4π 2 
= 2% = ± 2 × 10 –2
= ± 3% = ± 3 × 10 –2
⇒ 
= 
+ 
= 2 × 10 –2 + 2 × 3 × 10 –2 = 8 × 10 –2 = ± 8 %
