Two blocks
A
and
B
, each of mass
m
are connected by means of a pulley-spring system on a smooth inclined plane of inclination
\theta
as shown in the figure. The spring and all the pullies are ideal. Now,
B
is slightly displaced from its equilibrium position. It starts to oscillate. Time period of oscillation of
B
will be
n\pi
. Value of
n
is equal to
q,
. (Take
m=4kg,K=5(N)/(m)
)
