State Gauss' Law
A spherical volume carries a uniform charge density [itex]\rho_0[/itex]. A particle of mass m and charge -q is placed inside the sphere at radial distance r. (This additional charge does not distort the field arising from the [itex]\rho_0[/itex] charge density.) Show that the particle oscillates harmonically and find its' oscillation frequency.
don't really know what to do here.
obviously gauss' law is [itex]\nabla \cdot \vec{E}=\frac{\rho_0}{\epsilon}[/itex]
and the lorentz force will probably come into play, [itex]F=\int_V \rho_0 \vec{E} dV[/itex] seeing as ther's no magnetic field.
but i can't put it together.
thanks guys.
