Question

In an experiment time period of a simple pendulum are measured as 2.63s, 2.56s, 2.71s,2.80s. Find average absolute error and the percentage error

Answer 1

Explanation:

T=

5

2.63+2.56+2.42+2.71+2.80

5

13.12

=2.624=2.62

2.62−2.63=−0.01

2.62−2.56=+0.06

2.62−2.42=+0.20

2.62−2.71=−0.09

2.62−2.80=−0.18

Average absolute error

5

0.01+0.06+0.20+0.09+0.18

0.545=0.108=0.11s
