electric charges/ exert forces on each other when they are distances apart
1 of 10
What is an electric field?
region where an electric charge will experience a force
2 of 10
What doe the magnitude of an electric field depend on?
charge and strength of the field
3 of 10
Define electric field strength
the force per unit per positive charge
4 of 10
Describe electric field lines
+ to -
5 of 10
What is coulombs law?
two point charges exert an electric force on each other that is directly prop to the product of the charges and inversely proportional to the separation
6 of 10
Describe an uniform electric field
acceleration of charged particles is constant/ if + the acceleration will be in the direction of the field/ if - it will be opposite
7 of 10
Describe the similarities between gravitational and electric fields
inverse square laws depending on distance/ both show uniform fields/ both show radial fields
8 of 10
How are electric fields and circular motion related?
F = Electric field strength as it is a force!
9 of 10
What are the differences between gravitational and electric fields?
grav fileds arise from masses/ electric from charges// grav are only attractive - elec can be either
