A light sprial spring supports `200g` weight at its lower end oscillates with a period of `1s`. The weight that must be removed from the lower end to reduce the period to `0.5s` is

Three mass 0.1 kg ,0.3 kg and 0.4 kg are suspended at end of a spring. When is 0.4 kg mass is removed , the system oscillates with a period 2 s . When the 0.3 kg mass is also removed , the system will oscillates with a period

Three mass 0.1 kg ,0.3 kg and 0.4 kg are suspended at end of a spring. When is 0.4 kg mass is removed , the system oscillates with a period 2 s . When the 0.3 kg mass is also removed , the system will oscillates with a period

Three masses of 500 g , 300 g and 100 g are suspended at the end of a spring as shown and are in equilibrium. When the 500 g mass is removed suddenly, the system oscillates with a period of 2 s . When the 300 g mass is also removed, it will oscillate with period T . Find the value of T .

A srting of length l hangs freely from a rigid support under its own weight Calculate the time required by transverse waves to travel from the lower end to the upper end

1 kg weight is suspended to a weightless spring and it has time period T. If now 4 kg weight is suspended from the same spring the time period will be
