According to a mathematical model,the spring constant k, of a spring can be written as: k=\frac{4 \pi^{2} m}{T^{2}} where T is the period of oscillation of amass m attached to

a spring.You want to estimate the value of k with minimum uncertainty possible by making graphs. What would be the main step in your method to get the desired result? O Time the period of one oscillation of the mass and use it to calculate k. Repeat it to get several k and plot the k. O Time the period of one oscillation of several masses and plot the period and masses O Time the period of many oscillations of a mass to find one average period. Repeat the experiment for several masses and make appropriate plot O Time the period of many oscillations of a mass to find one average period and use it to calculate k. Repeat it to get several k and calculate average k
