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.

Set the initial x velocity to zero and the initial y velocity to 5 m/s. Set the electric field to 2 V/m, and the charge to +1x10-5 C. Predict the motion of the charge. Check your prediction.

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.
