Electrostatics Flashcards
Define charge
- One of the basic properties of the elementary particles of matter
- giving rise to all electric and magnetic forces and interaction
Define ELECTROSTATIC charge
- Electric charge at rest
- on the surface of an insulated body
Define electric force field
- the region around a charged particle or object
- in which it exerts a force on another charged particle or object
What is the direction of the electric field (at a point)?
the direction that a positive test charge would move if placed at that point
Define electrostatic force
the force exerted by non-moving (static) charges on each other
What is the Basic Law of Electrical Charge?
- like charges repel each other
- unlike charges attract each other
What is the Law of Conservation of Charge?
- the net charge
- of an isolated system
- remains constant
Q of one electron =
-1,6 x 10^-19
Q of one proton =
+1,6 x 10^-19
no. of particles =
total charge / charge on one particle
total charge =
no. of particles x charge on one particle
charge on one particle =
total charge / no. of particles
Great electron affinity
when atoms of a substance attract some electrons from the other substance to itself
Define triboelectric series
a series that compares abilities of substances to lose of gain electrons by friction
Effects of electrostatic forces can be…
attractive or repulsive
