Physics Question on simple harmonic motion
A Simple pendulum experiment is performed for the value of 'g',the acceleration due to the earth's gravity. The measured value of length of the pendulum is 25 cm with an accuracy of 1 mm and the measured time for 100 oscillations is found to be 100 sec with an accuracy of 1 sec. The percentage uncertainty in the determination of 'g' is:
A
9.8
B
0.98
C
4.8
D
2.4
E
1.4
Answer
2.4
