Question

To measure gravitational acceleration by using simple pendulum, length of pendulum (0.8
0.01) m and periodic time (2.5 + 0.12) s. Find percentage error in measurement of g.
(A) 10.85 %
(B) 12.75 %
(C) 15.85 %
(D) 21.12 %​

Answer 1

Answer:

If the length of pendulum is 0.8+/-0.01m and time peroid is 2.5+/-0.012 sec. Then percentage error in acceleration due to gravity will be..

Error Analysis

Error Analysis is a method of finding out the error in the final result when the quantities with an error are added, subtracted, multiplied or divided or undergoes any other mathematical operation.
