Frequency of a particle performing S.H.M. is 10 Hz . The particle is suspended from a vertical spring. At the highest point of its oscillation the spring is unstretched. Maximum speed of the particle is ( g =10 ~m / s ^2 )
Options
- A1 ~m / s
- B1 2 ~m / s
- C1 4 ~m / s
- D2 ~m / s
Correct answer
B. 1 2 ~m / s
Step-by-step solution
