An object with a charge of -30c and a mass of 17times102kg

Question

An object with a charge of -3.0C and a mass of 1.7×10²kg experiences an upward electric force, due to a uniform electric field, equal in magnitude to its weight.

Part A discovers the magnitude of the electric field.

Parts B discover the direction of the electric field.

Part C If the electric charge on the object is doubled while it’s mass remains the same, discover the direction and magnitude of its acceleration.

Part D If the electric charge on the object is doubled while it’s mass remains the same, discover the direction and magnitude of its acceleration.
