An experiment is performed to obtain the value of acceleration due to gravity g by using a simple pendulum of length L. In this experiment time for $\displaystyle 100$ oscillations is measured by using a watch of $\displaystyle 1$ second least count and the value is $\displaystyle 90.0$ seconds. The length L is measured by using a meter scale of least count $\displaystyle 1$ mm and the value is $\displaystyle 20.0$ cm. The error in the determination of g would be :
