A spring mass system oscillates with a time period T1 when a certain mass is attached to the spring. When a different mass is attached after removing the first mass the time period becomes T2. When both the masses are attached to the free end of the spring with the other end fixed, the time period of oscillation is :

Q2
A body at the end of a spring executes S.H.M. with a period t1, while the corresponding period for another spring is t2. If the period of oscillation with the two springs in series is T, then

Q3
A block of mass 'm' is suspended by different springs of spring constants shown in the figure.
Let time period of oscillation in these four positions be T1, T2, T3 and T4. Then

Q4
A uniform spring has certain mass suspended from it and its period for vertical oscillation is T1. The spring is now cut into two parts having the lengths in the ratio of 1 : 2 and a mass m is suspended with these two springs as shown in the figure. Now, time period is T2. The ratio T1/T2 is:

Q5
A body of mass m is attached to the lower end of a spring whose upper end is fixed. The spring has negligible mass. When the mass m is slightly pulled down and released, it oscillates with a time period of 3s. When the mass m is increased by 1kg, the time period of oscillation becomes 5s. The value of m in kg is
