A particle of mass m is under the influence of a force $F$ which varies with the displacement $x$ according to the relation $F = - kx + {F_0}$ in which $k$ and ${F_0}$ are constants. The particle when disturbed will oscillate
  • Aabout $x = 0,\,{\rm{with }}\,\omega \ne \sqrt {k/m} $
  • Babout $x = 0,\,{\rm{with }}\,\omega = \sqrt {k/m} $
  • Cabout $x = {F_0}/k\,\,{\rm{with }}\,\omega = \sqrt {k/m} $
  • Dabout $x = {F_0}{\rm{/}}k\,{\rm{with }}\,\omega \ne \sqrt {k/m} $
