An object with a charge of -2.6?C and a mass of 1.2×10?2kg experiences an upward electric force, due to a uniform electric field, equal in magnitude to its weight.
Part 1: Find the magnitude of the electric field in N/C
Part 2: If the electric charge on the object is doubled while its mass remains the same, find the direction and magnitude of its acceleration in m/s^2.
