An object of mass 3 ~kg is executing simple harmonic motion with an amplitude 2 m . If the kinetic energy of the object when it crosses the mean position is 6 ~J , the time period of oscillation of the object is
Options
- A1 ~s
- B2 ~s
- C3 ~s
- D4 ~s
Correct answer
B. 2 ~s
Step-by-step solution
Mass of object, m =3 ~kg Amplitude, A= 2 m Kinetic energy =6 ~J Kinetic energy = 1 2 m ^2 A^2=6 aligned & 1 2 3 4 ^2 ~T ^2 4 ^2 =6 & T ^2=4 ; T =2 ~s aligned
