An electron remains suspended between thesurface of the Earth (assumed neutral) and afixed positive point charge, at a distance of4.99 m from the point charge.Determine the charge required for thisto happen. The acceleration of gravityis 9.8 m/s2 and the Coulomb constant is8.98755 × 109 N · m2/C2.Answer in units of C.
