Question

The time period of a mass suspended from a spring is T. If is the spring is cut into four equal parts and the same mass is suspend from one of the parts, then the new time period will be -

Answer 1

Time Period (1/4)* (T) = (1/2)*pi ( l/g)^.5 when the spring is cut into 4 parts.

When there are 4 parts that are combined into one mass then the Period of the conglomerate becomes into a product of (1/4) T *4.

The Time Period of the conglomerate is the Time period product of all 4 sub parts by the number sub parts: (1/4)T * 4 = T

: Time Period= T = 2*pi (l/g)^.5
