Question

In an experiment to determine the time period of oscillation for a simple pendulum is found out to be 1.5s,1.6s,1.8s,2.2s,2.1s and 2.4s.Find the relatiive error and the percentage error in the measurement.I need a step by step explaination!

Answer 1

Answer:

The computation of percentage error involves the use of the absolute error, which is simply the difference between the observed and the true value. The absolute error is then divided by the true value, resulting in the relative error, which is multiplied by 100 to obtain the percentage error.

Explanation:

The formula is: REaccuracy = (Absolute error / “True” value) * 100%. When expressed as a percentage (i.e. 96%), this is also called percent error. If you don't know the “true” measurement, you can use the first definition — precision — as a substitute

Explanation:

According to ohms law

v=ir

so, here v=72v

i=?

r=7+5(since it is connected in series)

so i= 72/12

=6ampere

now, v=6*5

=30
