Set the initial x velocity to zero, the initial y velocity to 5 m/s, and the magnetic field to zero. Set the electric field to -2 V/m, and the charge to 10 mC. Predict the motion of the charge. Check your prediction using the simulation.

Now set the initial x velocity to 5 m/s and run the simulation. How would the motion be different if the mass of the charged object were to double? Make your prediction and check it with the simulation.
