We know that
In the solenoid magnetic field along the axis of solenoid.
When charge particle moving inside solenoid along the axis \mathrm{F}=0

\overrightarrow{\mathrm{F}_{\mathrm{m}}}=\mathrm{q}(\overrightarrow{\mathrm{V}} \times \overrightarrow{\mathrm{B}})
So, \overrightarrow{\mathrm{F}_{\mathrm{m}}}=0

And it moves with constant velocity.
