Physics - Error Question with Solution | TestHub

The period of oscillation of a simple pendulum is given by$T=2\pi \sqrt{\frac{L}{g}}$, where$L$is the length of the pendulum and$g$is the acceleration due to gravity. The length is measured using a meter scale which has$500$divisions. If the measured value$L$is$50\mathrm{ }\mathrm{cm}$, the accuracy in the determination of$g$is$1.1\%$and the time taken for$100$oscillations is$100$seconds, what should be the possible error in measurement of the clock in one minute (in milliseconds)?
