An ionized gas contains both positive and negative ions . If it is subjected simultaneously to an electric field along the ` +x` - direction and a magnetic field along the ` +y` - direction and the negative ions towardws `-y` - direction

Positive ions deflect towards +y direction and negative ions towards -y direction

All ions deflect towards +y direction

All ions deflect towards -y direction

Positive ions deflect towards -y direction and negative ions towards +y direction
