Question

Three masses 500 ~g , 300 ~g and 100 g are suspended at the end of spring as shown in figure and are in equilibrium. When the 500 g mass is removed, the system oscillates with a period of 3 second. When the 300 g mass is also removed it will oscillate with a period of

Correct answer: A. 1 s

When 500 g is removed, ( m =(100+300) g =0.4 ~kg ) ( array ll & T=2 0.4 k =2 s & 2 k = 2 0.4 (i) array ) When 300 g is also removed, ( aligned m^ & =100 g=0.1 ~kg T^ & =2 0.1 k = 2 0.4 0.1 (using Eq. (i)) T^ & = 2 2 =1 s aligned )
