Write a note on combination of error.
Write a note on combination of error.
- When experiment involve several measurement, errors in all the measurement combine.
- For example, in measurement of density, error due to mass and volume will combine.
* Error combine in various mathematical operation like addition, subtraction, multiplication and division.

In a simple pendulum experiment for determination of acceleration due to gravity $(g)$, time taken for $20$ oscillations is measured by using a watch of $1\, second$ least count. The mean value of time taken comes out to be $30\,s$. The length of pendulum is measured by using a meter scale of least count $1\, mm$ and the value obtained is $55.0\, cm$. The percentage error in the determination of $g$ is close to ........... $\%$
