Frequency of oscillation is proportional to

Options

  1. A3 k m
  2. Bk m
  3. C2 k m
  4. Dm 3 k

Correct answer

A. 3 k m

Step-by-step solution

Let mass is displaced towards left by x then force on mass =- kx -2 kx =-3 kx [negative sign is taken because force is opposite to the direction of motion] array l F =-3 kx =- m ² x = 3 k m f = 2 = 1 2 3 k m array Thus it is propotional to 3 k / m
