The time period of small oscillations of mass `m` :-

A

`2pisqrt((m)/(6k))`

B

`2pisqrt((11m)/(6K))`

C

`2pisqrt((6m)/(11K))`

D

`2pisqrt((m)/(K))`

Text Solution

Verified by Experts

The correct Answer is:
B
Equivalent spring constant `(1)/(K_(eq)) = (1)/(3K) + (1)/(2K) + (1)/(K) rArr K_(eq) = (6K)/(11) :. T 2pisqrt((m)/(K_(eq))) = 2pisqrt((11m)/(6K))`

A light pulley is suspended at the lower end of a spring of constant k_(1) , as shown in figure. An inextensible string passes over the pulley. At one end of string a mass m is suspended, the other end of the string is attached to another spring of constant k_(2) . The other ends of both the springs are attached to rigid supports, as shown. Neglecting masses of springs and any friction, find the time period of small oscillations of mass m about equilibrium position.
