The frequency of oscillation (10π) (in Hz) of a particle of mass 0.1 kg which executes SHM along x-axis. The kinetic energy is 0.3 J and potential energy is 0.2J at position x = 0.02 m. The potential energy is zero at mean position. Find the amplitude of oscillations (in meters)

a
1210
b
110
c
10
d
210

detailed solution

Correct option is A

Etotal=m ω2A22 0.5= 0.1×4×π22×100π2×A2 So  A=1210m
