Question

Period of pendulum as recorded by student are 1.52 s, 1.5 s, 1.48 s then percentage error in measurement of time period is :​

Answer 1

Answer:

0 sec

Explanation:

T=$\frac{1.52 + 1.50 + 1.48}{3}$

=

$\frac{4.5}{3}$

=1.5

$1.5 - 1.52 = - 0.02$

$1.5 - 1.5 = 0$

$1.5 - 1.48 = + 0.02$

Average absolute error:

$= \frac{ - 0.02 + 0 + 0.02}{3}$

$= \frac{0}{3}$

$= 0s$
