Two identical springs are fixed at one end and masses `1kg` and `4kg` are suspended at their other ends. They are both strethced down form their mean position and let go simultaneously. If they are in the same phase after every `4` seconds then the springs constant `k` is

Two springs fixed at one end are stretched by 4 cm and 12 cm, respectively, when masses of 0.5 kg and 1 kg are suspended at their lower ends. They are displaced slightly from their mean positions and released. What is the ratio of their periods of oscillation ?

Two identical springs of force constant "k" are joined one at the end of the other (in series). Find the effective force constant of the combination.

From the fixed pulley, masses 2kg, 1kg and 3kg are suspended as shown in the figure. Find the extension in the spring if k=100 N//m . (Neglect oscillations due to spring)

A spring of spring constant 'k' is supported from one end and tied by a mass 'm' at the other end. Write the formula to find the period of oscillation of the mass body. (Ignore the mass of the spring).

A spring of spring constant 'k' is used to suspend a mass 'm' at its free end while the other end of the spring is rigidly fixed. If the mass is slightly depressed and released, then name the motion of the mass.

spring of force constant k clamped rigidly at onoe end and a mass m attached to its free end. A force F applied at the free end stretches the spring. Figure shows the same spring with both ends free and attached to a mass m at either end. Each end of the spring in figure is stretched by the same force F. (a) What is the maximum extension of the spring in the two cases ? (b) If the mass in figure and the two masses in figure are released free, what is the period of oscillation in each case?

Figure a) shows a spring of force constant k clamped rigidly at once end and a mass m attached to its free end. A force F applied at the free end stretches the spring.
