The diagram shows cathode rays entering an electric field between two charged plates.
How does the path of the cathode rays change and why?
1 )
They move towards the negative plate because cathode rays have a negative charge.
2 )
They move towards the negative plate because cathode rays have a positive charge.
They move towards the positive plate because cathode rays have a negative charge.
4 )
They move towards the positive plate because cathode rays have a positive charge.
