A charged particle enters a magnetic field from the left in the positive x-direction as shown below. The particle curves downward on the page in the negative y-direction as it enters the field. What direction would an electric field need to be added to the magnetic field region so that the particle travels straight through the magnetic field in the positive x-direction without changing direction? The electric field would be directed in the positive x-direction. The electric field would be directed in the positive y-direction. The electric field would be directed in the negative y-direction. The electric field would be directed in the positive z-direction.
