Four massless springs whose force constants are 
, 
, and 
, respectively are attached to a mass 
, kept on a frictionless plane (as shown in figure). If the mass 
is displaced in the horizontal direction, then find the frequency of the system.
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
B
Spring on the left of the block are in series, hence there equivalent is
Springs on the right of the block are in parallel, hence there equivalent is
Now again both 
and 
are in parallel
Hence, frequency is
