Question

Suppose a beam contain all three particle and allowed to move

Answer 1

Answer:

A particle beam directs towards the positive field it means it has an opposite charge which is negative hence,it gets  attracted towards the positive electric field and the particle having negative charge is electron so we conclude that the A beam has particles called electron.

A particle beam which attracts towards the negative field must be containing positive charge particles that is protons

And the particle beam not getting deflected must be neutral and it is neutron so

A is electron

B is neutron

C is proton
