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

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 100 oscillations is measured by using a watch of 1 second least count and the value is 90.0 seconds. The length L is measured by using a meter scale of least count 1 mm and the value is 20.0 cm. The error in the determination of g would be:
