Study Notes
Fundamental Charge Properties
- The principle of quantization states that the charge of an object is always a multiple of the elementary charge (e).
- Additivity refers to the ability to combine charges, indicating that the total charge of a system is the arithmetic sum of individual charges.
Quantization of Charge
- Charge is quantized, meaning it can only exist in discrete values rather than continuously.
- The term 'charge can be broken down into smaller individual charges' describes the integral nature of charge, stemming from its quantization.
- If a body has a net charge +Q, it indicates that a specific number of elementary charges have been removed, corresponding to the charge's quantization.
Conservation of Charge
- The total charge in an isolated system remains constant over time, affirming the law of conservation of charge.
- The algebraic sum of the charges in the system remains unchanged, represented by 'const/same,' reflecting that total charge is unchanged in a closed system.
Charge Calculations
- The total charge of an isolated system is determined to be zero when all positive and negative charges balance each other out.
- If a charge of $-3 \times 10^{-19}$ is added to $5 \times 10^{-19}$, the resulting algebraic sum is $2 \times 10^{-19}$.
Example Charge Problems
- In a system where one charge is $-4 \times 10^{-19}$ and the total charge is $-1.5 \times 10^{-19}$, the other charge can be calculated as $2.5 \times 10^{-19}$.
- If one charge in a system is $2 \times 10^{-19}$ and the total charge is $4 \times 10^{-19}$, the unknown charge is $2 \times 10^{-19}$.
- With a net charge of $0$ and known charge $3 \times 10^{-19}$, the unknown charge must be $-3 \times 10^{-19}$ to balance the system.
Additional Numerical and Coded Information
- The total numerical value derived from the provided text relates to essential insights derived from charge quantization.
- The product of numbers 50, 4, 6, and 10 results in 12000.
- The letter 'm' appears multiple times in the text.
- If the number 12 represents 'A', the coding for 'charged halved' would depend on a coding scheme relating letters to numbers.
- In the sequence 19, 8, _, 12, 22, the missing number is 15.
Charge Values and Relationships
- According to quantization, total charge on a body must be an integral multiple of the elementary charge (charge on an electron).
- If a body's total charge is not an integral multiple of e, it indicates a violation of fundamental charge quantization.
- If the total charge of a system is $-4 \times 10^{-19}$ and contains a charge of $7 \times 10^{-19}$, the other charge must be $-11 \times 10^{-19}$.
