Answer:
The magnitude of the acceleration is equal to 19.6m/s² and the acceleration is directed upwards though the magnitude of the charge has doubled. This is because the electric force is directed upwards and from newton's second law of motion the charge will have acceleration in the same direction as the electric force on the charge.

Answer:
m = 7000 - 500 = 6500 g
ρ = m/v = 6500 gm / 500 cm³ = 1.3 g/cm³
The paint brush floats because its density is less than that of the paint and has displaced its weight in the paint.
