While measuring the acceleration due to gravity by a simple pendulum, a student makes a positive error of 1% in the length of the pendulum and a negative error of 3% in the value of time period. His percentage error in the measurement of 
by the relation 
will be
Text Solution
Verified by ExpertsThe correct answer is:
C
Percentage error in g = 
+ 2(% error in T )= 1% + 2(3%) = 7%
