Scientific prediction:
Predict the path of a beam of subatomic
particle as it passes through an electric field
formed by two plates one is positively
charged and the other is negatively charged:
The electrons :are deviated towards the
positive plate because they are negatively
charged and the differed charges’re attracted.
The Neutrons: pass in a straight line without deviation
because they are neutrally charged.
The proton: are deviated towards the negative plate
because they are positively charged and the different charges’re attracted.
Life application: Based on The Attraction of Opposite Electric Charges.
The Electrostatic Plating:
Importance: Metal plating
Working Idea: 1-The object to be plated is charged with
a negative electric charge
-The paint spray is charged with a positive electric charge
2- When sprayed, the paint particles are attracted to the object to be
plated due to the difference in their charges.
Advantages:
1. Ensures an even layer of paint 2. Reduces paint waste
