 A point charge Q with a mass of m = [m] kg is submerged in a uniform electric field pointed vertically downward. Q = -[x] C. If the net force applied on the charge is zero, what is the magnitude of the electric field (unit in N/C)? Gravitational acceleration g = 9.8 m/s2. Note that magnitude is positive.
