3 types of fields
Electric fields
Magnetic fields
Gravitational fields
Fields are vectors or scalers?
VECTORS
Define Field
A region in which an object experiences a force
Define electric field
A region in which a CHARGE experiences a force(electric force)
Electric fields are produced by what?
CHARGES
In an electric field when you keep a second charge what will the second charge experience
Second charge experiences a force on it (ELECTRIC FORCE)
To find direction of electric field at a point…
Draw tangent on eletric field line at the point
Field lines give?
1.)strength (magnitude) of electric field
2.) direction of electric field
Define electric field strength
Force per unit positive charge
E=F/Q
Vector
Uniform electric field
Everywhere electric field strength is the SAME
Strength of uniform electric fields
E=V/d
Unit: vm-1
Can apply E=F/Q
