Question

The acceleration of particle in SHM at 5 cm from its mean position 20cm the value of angular velocity will be

Answer 1

Answer will be 2cm (+/-).

Answer 2

Answer: 4 radian/sec

Explanation: a=ω²×

          a = 20 cm/sec²

          × = 5 cm

          so, ω = 2 radian/sec → which means 2 rotations per second

      the angle swipped in 2 full raotations will be 4π

      and T = 2π/ω = 2π/2 = π

      ANGULAR VELOCITY = angle swipped / time taken

                                          = 4π / π = 4 radian / sec
