The length of a pendulum is measured as 1.01 m and time for 30 oscillations is measured as one minute 3 seconds. Error lengths is 0.01 m and error in time is 3 secs.The percentage error in the measurement of acceleration due to gravity is

The displacement of a particle executing SHM is given by y = 5 sin (4t + π/3 ) of T is the time period and the mass of the particle is 2 gms, the kinetic energy of the particle when t = T/4 is given by

The magnitude of maximum acceleration is π times that of maximum velocity of a simple harmonic oscillator. The time period of the oscillator in seconds is
