When a mass m is hung on a spring, the spring stretched by 6 cm. If the loaded spring is pulled downward a little and released, then the period of vibration of the system will be

When a body of mass M is hung from a spring, the spring extends by 1 em. If the body of mass 2M be hung from the same spring, the extension of spring will be

A 4-kg block extends a spring by 16 cm from its unstretched postion .The block is removed and a 0.5 -kg boby is hung from the same spring If the spring is then stretched and released , what is the time period of oscillations of the mass suspendrd ? What is the force constant of the spring ?

When a 1.0kg mass hangs attached to a spring of length 50 cm, the spring stretches by 2 cm. The mass is pulled down until the length of the spring becomes 60 cm. What is the amount of elastic energy stored in the spring in this condition. if g = 10 m//s^(2).

When a 1 kg mass is hung from a spring 50 em long, it stretches by 2 cm. The mass is then pulled down until the length of spring becomes 60 cm. The amount of clastic energy stored in the spring in this condition when g is 10 ms^(-1) can be given as

The young modulii of two springs of equal length and equal cross sectional areas are in the ratio 2:3 both the springs are suspended and loaded with the same mass . When springs are stretched and released , the time period of oscillation of the two springs is in the ratio of
