How does an object become negatively charged?
An object becomes negatively charged by gaining extra electrons.
How does an object become positively charged?
An object becomes positively charged by losing electrons, resulting in more protons than electrons.
What are the steps to find the net force on a charge due to multiple charges at an angle?
- Resolve forces into x and y components. 2. Find the net force in the x-direction (Fx_net) and y-direction (Fy_net). 3. Use the Pythagorean theorem to find the magnitude of the net force: F_net = sqrt(Fx_net^2 + Fy_net^2). 4. Use trigonometry to find the direction of the net force.
Compare and contrast the force between like charges and unlike charges.
Like charges: Repel each other. | Unlike charges: Attract each other.
What is the effect of increasing the distance between two charges on the electric force between them?
The electric force decreases (inversely proportional to the square of the distance).
What is the effect of increasing the magnitude of either charge on the electric force between them?
The electric force increases (directly proportional to the product of the charges).
What happens when an atom gains extra electrons?
The atom becomes negatively charged.
What happens when an atom loses electrons?
The atom becomes positively charged.
