Which one of the following equations of motion represents simple harmonic motion? Where k,k0,k1\mathrm{k}, \mathrm{k}_0, \mathrm{k}_1 and a\mathrm{a} are all positive

Options

  1. AAcceleration =kx=\mathrm{kx}
  2. BAcceleration =−k0x+k1x2=-\mathrm{k}_0 \mathrm{x}+\mathrm{k}_1 \mathrm{x}^2
  3. CAcceleration =−k(x+a)=-\mathrm{k}(\mathrm{x}+\mathrm{a})
  4. DAcceleration =k(x+a)=k(x+a)

Correct answer

C. Acceleration =−k(x+a)=-\mathrm{k}(\mathrm{x}+\mathrm{a})

Step-by-step solution

In SHM,Frestoring ∝−\mathrm{SHM}, \mathrm{F}_{\text{restoring }} \propto-X\mathrm{X}
