A particle executing SHM while moving from one extremity is found to be at distances x₁, x₂ and x₃ from the mean position at the end of three successive seconds. The time period of oscillation is ('  ' used in the following choices is given by  )

A block of mass m is suspended by different springs of force constant shown in figure. Let time period of oscillation in these four positions be and . Then

A pendulum has time period T for small oscillations. An obstacle P is situated below the point of suspension O at a distance . The pendulum is releases from rest. Throughout the motion the moving string makes small angle with vertical. Time after which the pendulum returns back to its initial position is

A mass m=8 kg is attached to a spring as shown in figure and held in position so that the spring remains unstretched. The spring constant is 200 N/m. The mass m is then released and begins to undergo small oscillations. The maximum velocity the mass will be
