We measure the period of oscillation of a simple pendulum. In successive measurements, the readings turn out to be 2.63 s, 2.56s, 2.42s, 2.71s and 2.80 s. Calculate the
(a) absolute errors, (b) relative error  (c) percentage error

Explanation

(a) 0.01s , 0.06 s, 0.20 s, 0.09 s, 0.18 s
(b) .04
(c) 4%
