Assignment:
An object with a charge of -3.6 micro C and a mass of 0.012 kg experiences an upward electric force, due to a uniform electric field, equal in magnitude to its weight. (a) Find the direction and magnitude of the electric field. (b) If the electric charge on the object is doubled while its mass remains the same, find the direction and magnitude of its acceleration.
Provide complete and step by step solution for the question and show calculations and use formulas.
