Question : 100 of 100

Marks: +1, -0

T

n

Solution:

Let the spring constant of the original spring be

k

Then its time period

T=2\pi\sqrt{\frac{m}{k}}

where

m

is the mass of oscillating body.

When the spring is cut into

n

equal parts, the spring constant of one part becomes

n k

. Therefore the new time period,

T'=2\pi\sqrt{\frac{m}{nk}}=\frac{T}{\sqrt{n}}
