The block then takes time tdown to slide back down to the bottom of the ramp, where it has speed Uf. while plasma is never neutral, it can either be positively or negatively charged. The work done by friction while sliding down the ramp will be the same expression you used to determine the work done moving up the ramp since the force of friction and distance over which it acts are the same in both directions of travel.
