" Find equivalent spring constant for the system "

What will be the equivalent spring constant of the spring system shown in the figure ?

Find the equivalent spring constant for the following arrangements:

The figure shows the arrangement of three springs of different spring constant, connected to a mass m. When mass m oscillates find equivalent spring constant and the time period of vibration.

Find the time period of the oscilltion of mass m in figure a and b. What is the equivalent spring constant of the spring in each case. ?

Find the equivalent spring constant in the following cases:

Two springs of spring constant k_(1)" and "k_(2) are joined in series. Hence its equivalent spring constant of the combination is…………
