Time period of a spring-block system is given by \(T = 2\pi\sqrt{\dfrac{m}{k}}\). If mass of the block is given by \(m = 10\,\text{g} \pm 10\,\text{mg}\) and time period is measured using a stopwatch having least count of \(2\,\text{s}\) and was found to be \(60\,\text{s}\) for \(50\) oscillations, then find the % error in measurement of \(k\).
