1. An object with a charge of -2.9 microC and a mass of .012 kg experiences an upward electric force, due to a uniform electric field, equal in magnitude to its weight. Part A: Find the magnitude of the electric field. Which I correctly calculated to be 4.1 x 10^4 N/C. Part B: If the electric charge on the object is doubled while its mass remains the same, find the direction and magnitude of its acceleration. 2. F=ma 3. I'm not really sure how to calculate the acceleration of the problem. Any ideas?
