One body is suspended from a spring of length `l`, spring constant `k` and has time period `T`, Now if spring is divided in two equal parts which are joined in paralled and the same body is suspended from this arrangements then determine new time period.

Spring constant in parallel combination `k' = 2k + 2k = 4k` `:. T = 2pisqrt((m)/(k')) = 2pisqrt((m)/(4k)) = 2pisqrt((m)/(k)) xx (1)/(sqrt(4)) = (T)/(sqrt(4)) = (T)/(2)`

The time period of mass suspended from a spring is T. If the spring is cut into four equal parts and the same mass is suspended from one of the parts, then the new time period will be…….
A mass m suspended at the end of spring of spring constant k and oscillate at periodic time T. If spring is cut into two part of equal length and tow pails are now connected in parallel and a block is suspended at the end of the combined spring and oscillate then find new periodic time.
If a spring has time period T, and is cut into (n) equal parts, then the time period of each part will be.
Periodic time of oscillation T_1 is obtained when a mass is suspended from a spring if another spring is used with same mass then periodic time of oscillation is T_2 . Now if this mass is suspended from series combination of above spring then calculate the time period.
Let T_(1)" and "T_(2) be the time periods of spring A and B when mass M is suspended from the end of the spring. If both springs are taken in series and the same mass M is suspended from the series combination, the time period is T, then
A mass M is suspended from a light spring. An additional mass m added to it displaces the spring further by distance x then its time period is
On end of a light spring of natural length d and spring constant k is fixed on a rigid wall and the other is attached to a smooth ring of mass m which can slide without friction on a vertical rod fixed at a distance d from the wall. Initially the spring makes an angle of 37^@ with the horizontal. as shown in figure. When the system is released from rest, find the speed of the ring when the spring becomes horizontal. (sin 37^@=3/5) .
