A load attached to the end of a spring and in equilibrium produces 9 cm extension of spring. If the spring is cut into three equal parts and one end of reach is fixed at 'O' and other ends are attached to the same load, the tension in cm of the combination in equilibrium now is :

"A mass is attached to one end of a spring and by holding the other end in hand, the spring is whirled in a horizontal circle" What happens to the length of the spring ?

A spring having a spring constant k is loaded with a mass m. The spring is cut into two equal parts and one of these is loaded again with the same mass. The new spring constant i

A loaded spring vibrates with a period T. The spring is divided into four equal parts and the same load is divided into four equal parts and the same load is suspended from one end of these parts. The new period is

To one end of a massless spring, a body of mass m is attached. Now the spring is divided into two equal parts and to one of the parts the same body of mass m is attached. Determine the ratio of the frequencies of vibration in the two cases.

A spring having a spring constant K is loaded with mass m. The spring is in two equal parts and one of them is loaded with the same mass. The new spring constant is

a mass m is suspended at one end of a spring and the other end of the spring is fimly fixed on the celling. if the mass is slightly depressed and released it will execute oscillation. If the spring is cut into two equal halves and one half of the spring is used to suspend the same mass then obtain an expression for the ratio of periods of oscillation in two cases.
