Charge
In the context of conservation of charge, what happens when one charged system interacts with another identical charged system?
Charge remains the same
If a system has a total charge of 6.25x10^18, how much charge would each identical system have in a pair of interacting systems?
$3.125 \times 10^{18}$
What happens to the total charge when an isolated system interacts with another system that is not identical?
Total charge remains the same
If a charged system interacts with another identical charged system and the total charge is 100 N, what is the individual charge on each system?
$50$ N
Study Notes
Properties of Charge
- Charge is a scalar quantity.
- Charge is additive, meaning the total charge of a system is the sum of the individual charges.
Quantisation of Charge
- Charge is quantized, meaning it comes in discrete packets (quanta).
- The charge on a body is an integer multiple of the charge on an electron (e).
- The total charge on a system is given by the algebraic sum of the charges (with signs).
Conservation of Charge
- The total amount of charge on an isolated system is conserved.
- Charge cannot be created or destroyed, only transferred from one body to another.
Electronic Charge
- The magnitude of the electronic charge (e) is 1.6 × 10^-19 C.
- The charge on an electron is -e, while the charge on a proton is +e.
Units and Measurements
- The unit of charge is the coulomb (C).
- The mass of an electron is 9.1 × 10^-31 kg, while the mass of a proton is 1.6 × 10^-27 kg.
Types of Charge
- There are two types of charge: positive and negative.
- A body with no net charge is said to be neutral.
- A body with an equal number of positive and negative charges is also neutral.
This quiz covers topics related to types of charge in physics including extrinsic charge, intrinsic charge, and the properties of charged bodies. It also includes information about electronic charge and subatomic particles like electrons, protons, and neutrons.
