A proton beam travels from north to south, and an electron beam travels from south to north. Neglecting the magnetic field of the earth, the electron beam will be deflected

Step-by-step solution

The direction of electric current is taken as the direction of flow of positive charge. The proton beam travels from north to south, so the current due to it is from north to south. The electron beam travels from south to north. Since electrons are negatively charged, the current due to the electron beam is opposite to its direction of motion, which is also from north to south. Both beams represent parallel currents flowing in the same direction. Since parallel currents in the same direction attract each other, the
