Solve the each part of given problem:
Problem: An object with a charge of -3.1\mu C and a mass of 1.0 x 10-2 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.
Part B: Find the direction of the electric field if the electric charge on the object is doubled while it's mass remains the same.
Part C: Find the direction and magnitude of its acceleration. If the electric charge on the object is doubled while it's mass remains the same.
Part D: Find the direction and magnitude of its acceleration.
If possible just a brief explanation how you got the solution for above problem?
