question

An electric field E→\vec{E} with an average magnitude of about $150 \mathrm{~N} / \mathrm{C}$ points downward in the atmosphere near Earth's surface. We wish to "float" a sulfur sphere weighing $4.4 \mathrm{~N}$ in this field by charging the sphere. What charge (both sign and magnitude) must be used?
