An object with a charge of -4.4?C and a mass of 1.7×10?2kg experiences an upward electric force, due to a uniform electric field, equal in magnitude to its weight.
A) Find the magnitude of the electric field.
B) Find the direction of the electric field.
C) If the electric charge on the object is doubled while its mass remains the same, find the direction and magnitude of its acceleration.
D) If the electric charge on the object is doubled while its mass remains the same, find the direction and magnitude of its acceleration.
