You have a light spring, a metre scale and a known mass. How will you find the time period of oscillation of mass without the use of a clock ? |

Answer» Suspended the known mass from one end of spring whose another end is connected to a rigid ceiling. Note the extension l in the spring with the help of metre scale. If k is the spring constant of the spring, then in equlibrium position, `kl=mg or (m)/(k)=(l)/(g)` Tiem period of the loaded spring, `T=2pisqrt((m)/(k))=2pisqrt((l)/(g))` Knowling, the value of l, time period of oscillation T can be determined. |
