Question | Answer |
---|---|
Coulomb's Law | The magnitude of electric force between two points/charges. |
Electric Charge | A property that determines electrical behaviour, force exerted, and force experienced. |
Charge of Proton | Positive (+) |
Charge of Electron | Negative (-) |
Law of Charges | Like charges repel; Opposite charges attract |
Conductor | A material that can transmit electric charges. |
Electrostatic Charging | The changing or passing on of charge via friction, contact, induction, or polarisation. |
Electric Lines of Force | Imaginary lines formed by connecting electric field vectors at many points. Magnitude indicated by direction and proximity. Originate from positive charges and terminate at negative charges. |
In a uniform magnetic field, a particle who's initial veloticy is perpendicular to the field moves in what way? | A circular motion. |
Formula: Magnetic force on current carrying wire. | F=IlB Force = Current*Length of Wire*Magnetic Field Strength |
Left-Hand Rule | Point your fingers from North (Base of hand) to South (Fingertips). Point thumb in direction of particle. Palm indicates direction of magnetic field. Adjust as needed. |
Magnetic field between two wires? | 0 |
Magnitude of Electron's Charge? | e = 1.60e-19 C |
Formula: Coulomb's Law | Fe = (kq1q2)/r^2 |
Formula: Electric Field | E = F/q |
Coulomb's Constant | k = 8.99e9N*m^2/C^2 |
Charge positively? | By removing electrons. |
Charge negatively? | By adding electrons. |
Unlike charges ____ each other | attract |
Like charges ____ each other | repel |
