Electric Charge

Step 1: Understanding the Concept:
The net charge on an object is the algebraic sum of the charges of all its constituent particles. The charge of a single electron is -e, and the charge of a single proton is +e.

Step 3: Detailed Explanation:
An object contains 'x' electrons and 'y' protons.
The total charge due to 'x' electrons = .
The total charge due to 'y' protons = .
The net charge on the object is the sum of these charges:
Factoring out 'e', we get:

Step 4: Final Answer:
The net charge on the object will be (y - x)e.
