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

A

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

B

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

C

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

D

(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))`
