An object with a charge of -2.6 \mu C and a mass of1.7×10−2 kg experiences an upward electric force, due to a uniform electric field, equal in magnitude to itsweight.
A. Find the magnitude of the electricfield.
B. Find the direction of the electricfield.
C. If the electric charge on the object is doubled while its mass remains the same, find the direction and magnitude of its acceleration.
