A particle of mass m is under the influence of a force F which varies with the displacement x according to the relation F = -kx + F₀ in which k and F₀ are constants. The particle when disturbed will oscillate

Options :

1. About x = 0, with ω ≠ √(k / m)

2. About x = 0,with ω = √(k / m)

3. About x = F₀/k with ω = √(k / m)

4. About x = F₀/k with ω ≠ √(k / m)
