Three masses $$700$$ g, $$500$$ g and $$400$$ g are suspended at the end of a spring a shown and are in equilibrium. When the $$700$$ g mass is removed, the system oscillates with a period of $$3$$ seconds, when the $$500$$ g mass is also removed, it will oscillate with a period of

Question

Infinity Learn · Accepted Answer

When mass of $$700$$ g is removed, the left out mass (500$$ $$+$$ $$400) g oscillates with a period of $$3$$ $$sec$$.∴ $$3=t=2$$π(500+400)k$$ ……$$(i)When$$ $$500$$ g mass is also removed, the left out mass is $$400$$ gm.∴ t′$$=2$$$$π$$$$400k$$      .........$$(ii)⇒ $$3t$$′$$=900400$$⇒t′$$=2sec$$
