A block of mass 'm' is suspended by different springs of spring constants shown in the figure.
Let time period of oscillation in these four positions be T1, T2, T3 and T4. Then
T1= T2 =T4
T1= T2 and T3 =T4
T1= T2 =T3
T1= T3 and T2 =T4
Effective force constant in case (iii) and (iv) is
Let θ∈(0,π4) and t1=(tanθ)tanθ,t2(tanθ)cott3=(cotθ)tanθ and t4(cotθ)tanθ , then
