A small sphere with mass $5\mathrm{.}001077$ kgkg and charge $+6\mathrm{.}00$ CC is released from rest a distance of $0\mathrm{.}500$ mm above a large horizontal insulating sheet of charge that has uniform surface charge density $=+8\mathrm{.}00$ pC$/$m$2$pC$/$m$2.$Using energy methods, calculate the speed of the sphere when it is $0\mathrm{.}100$ mm above the sheet.

Express your answer to three significant figures and include the appropriate units.
